Alligators perform a spinning maneuver, referred to as a "death roll," to subdue their prey. In a study of alligator death rolls, one of the variables measured was the degree of the angle between the body and head of the alligator while performing the roll. A sample of rolls yielded the data provided below, in degrees. At the % significance level, do the data provide sufficient evidence to conclude that, on average, the angle between the body and head of an alligator during a death roll is greater than ? (Note: and s. Preliminary data analyses indicate that you can reasonably use a t-test to conduct the hypothesis test.)
Complete question :
Alligators perform a spinning maneuver, referred to as a "death roll," to subdue their prey. In a study of alligator death rolls, one of the variables measured was the degree of the angle between the body and head of the alligator while performing the roll. A sample of 20 rolls yielded the data provided below, in degrees. At the 1% significance level, do the data provide sufficient evidence to conclude that, on average, the angle between the body and head of an alligator during a death roll is greater than 45 ? Note: x =46.255° and s = 12.251° Preliminary data analyses indicate that you can reasonably use a t test to conduct the hypothesis test.
Answer:
H0 : μ = 45
H1 : μ > 45
T statistic = 0.4472
Pvalue = 0.3299
We fail to reject the Null
Step-by-step explanation:
H0 : μ = 45
H1 : μ > 45
Test statistic, T :
(xbar - μ) ÷ (s/√n)
(46.225 - 45) ÷ (12.251/√20)
1.225 ÷ 2.7394068
= 0.4472
Using the Pvalue calculator, the Pvalue can be obtained using the test statistic and degree of freedom
Degree of freedom, df = 20 - 1 = 19
Tscore = 0.4472
α = 0.01
Pvalue = 0.3299
Pvalue > α
0.3299 > 0.01 ; Hence, we fail to reject the Null
We fail to reject the Null; The data does not provide sufficient evidence to conclude that average angle between alligator's body and its head is greater than the 45

Answer:
3/4
Step-by-step explanation:
Well its a incomplete Question but i am solving a realted type Question .
• Find the slope of the line -3x - 4y = 12 :-
Ans ) The given equation can be converted into Slope intercept form , which is y = mx + c , where ,
m is slope c is y Intercept⇒ -3x -4y = 12
⇒ -4y = 12 +3x
⇒ y = 3x + 12 /4
⇒ y = 3/4x + 12/3
⇒ y = ¾x + 4
Comparing to Standard Form⇒ m = ¾
⇒ c = 4
Hence the slope of the line is 3/4.what is the slope of the line

A chi-square test of independence was conducted to investigate whether there is an association between the location where a person lives in a city (north, south, east, or west) and who the person planned to vote for in the upcoming mayoral election (the incumbent or the challenger). A random sample of 100 potential voters was selected, and the hypothesis test had a chi-square test statistic of x^2=9.84 with a p-value of 0.02. Which of the following statements is the correct interpretation of the pp-value in context?
a. There is a 2 percent chance that where a person lives and who that person plans to vote for are independent.
b. There is a 2 percent chance that where a person lives and who that person plans to vote for are dependent.
c. There is a 2 percent chance of making a Type IIII error.
d. Assuming that the location of where a person lives and who that person plans to vote for are dependent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.
e. Assuming that the location of where a person lives and who that person plans to vote for are independent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.
Answer:
The answer is "Option e".
Step-by-step explanation:
The Chi-Square Independence Test determines if the variables or linked among measurement items factors. It test is indeed not symmetric. It is also known as Interaction Chi-Square Test. Therefore it is also a 2% likelihood of obtaining a test statistic which is 9.84 or higher unless the place where a person is living, but for whom each plans to vote is different.
Represent each of these temperatures in degrees Fahrenheit with a positive or negative number. 5 degrees above zero 3 degrees below zero 6 degrees above zero 234 2 3 4 degrees below zero Order the temperatures above from the coldest to the warmest.
Answer:
5 degrees above Zero = greater than 0 = + 5
3 degrees below Zero = less than 0 = - 3
6 degrees above Zero = greater Than 0 = + 6
2 3/4 degree below Zero = less than 0 = - 2 3/4
-3 ; - 2 3/4 ; + 5 ; + 6
Step-by-step explanation:
5 degrees above Zero = greater than 0 = + 5
3 degrees below Zero = less than 0 = - 3
6 degrees above Zero = greater Than 0 = + 6
2 3/4 degree below Zero = less than 0 = - 2 3/4
The least temperature value implies the coldest while the highest implies the warmest :
Therefore.
Least temperature = - 3 ; then - 2 3/4 ; then + 5 ; then + 6
-3 ; - 2 3/4 ; + 5 ; + 6

Which of the following sets of vectors in R3 are linearly dependent?
Note. Mark all your choices.
9514 1404 393
Answer:
B, C
Step-by-step explanation:
Linearly dependent sets can be found using row-reduction techniques. If a row ends up zero, then the set is linearly dependent. Equivalently, the determinant of a 3×3 matrix can be computed. If it is zero, the set is dependent. The cross-product of two 3-D vectors can be computed. If it is zero, the vectors are dependent.
Any set of vectors that has more elements than each vector does must necessarily be dependent.
It is helpful to be able to use a calculator capable of performing these calculations (as opposed to doing it by hand). The first attachment shows the result of computing the reduced row-echelon form of the first set of 3 vectors. The set is found to be independent.
__
The second set of vectors is clearly dependent, as the second vector is 5 times the first.
__
The third set contains more vectors than there are elements to a vector. Hence at least one of them can be created using some combination of the others. This set is dependent.
__
The cross-product of the fourth set is non-zero, so it is independent. The second attachment shows the result of a row-reduction tool on these vectors.

This box-and-whisker plot shows the results.
Find median and range in the given box plot:
Answer:
Range = 45
Median = 75
Step-by-step explanation:
Based on the attached box and whisker plot :
From the plot :
Maximum value = 95
Minimum value = 50
The median value can be obtained from the box and whisker plot. The median value from the plot is ; the green dotted point inside the box :
This point is marked 75.
Hence, median value = 75
Range = maximum - minimum
Range =. 95 - 50 = 45

Given tan A= - and that angle A is in Quadrant IV, find the exact value of
sec A in simplest radical form using a rational denominator.
4
The secant of the angle A is 13/4
How to determine the value of sec(A)?The given parameter is:
[tex]\tan(A) = -\frac{\sqrt{153}}{4}[/tex]
Using the trigonometry identity, we have:
[tex]\sec^2(A) = \tan^2(A) + 1[/tex]
This gives
[tex]\sec^2(A) = (-\frac{\sqrt{153}}{4})^2 + 1[/tex]
Evaluate the exponent
[tex]\sec^2(A) = \frac{153}{16} + 1[/tex]
Evaluate the sum
[tex]\sec^2(A) = \frac{169}{16}[/tex]
Take the square root of both sides
[tex]\sec(A) = \pm \frac{13}{4}[/tex]
Secant in quadrant IV is positive.
So, we have:
[tex]\sec(A) = \frac{13}{4}[/tex]
Hence, the secant of angle A is 13/4

Answer:
1, 2: draw x as the altitude of a right triangle
3: draw x as double the altitude of the right triangle
Step-by-step explanation:
Consider the right-triangle geometry in the attachment. All of the right triangles are similar, so the ratios of corresponding sides are equal.
short side / long side = x/r = s/x
You may notice this compares to the required relation in problem 1.
__
If you multiply this out, you get ...
x² = rs ⇒ x = √(rs)
This compares to the required relation in problem 2.
__
So, you append the two line segments to each other so they make segment AB, find their midpoint D (using a perpendicular bisector construction), then draw the (semi-)circle centered at that midpoint. The perpendicular at X will intersect the circle at C, a distance of x from the line rs. (A perpendicular to a line at a point construction is required to create XC.)
__
For problem 3, you simply need to double the length √(rs) that you found in the previous constructions. A simple way to do this is to draw a circle, not a semicircle. Then point C' on the lower half of the circle will be 2√(rs) from point C.
