Answer:
A. A boxplot of the data has multiple large outliers.
D. A boxplot of the data shows a very slight skew.
Step-by-step explanation:
A) The normal distribution does not have outliers. The outliers are any point outside the 3σ interval which 99.7% of the data. The 0.3% data would not be outliers.
B) YEs the mean and median of the normal distribution are nearly equal. AS it is asymmetrical.
C) When the sample standard deviation is large the data is spread about the mean. The normal distribution is flatter and wider
D) The normal distribution is never skewed.If one end is longer then the distribution is not assymmetric and the normal distribution asymmetric meaning half is the mirror reflection of the other half.
So A and D indicate circumstances where he not be safe to use a t procedure.

Based on historical data in Oxnard college, we believe that 37% of freshmen do not visit their counselors regularly. For this year, you would like to obtain a new sample to estimate the proportiton of freshmen who do not visit their counselors regularly. You would like to be 98% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required
Answer:
A sample size of 1031 is required.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
37% of freshmen do not visit their counselors regularly.
This means that [tex]\pi = 0.37[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
You would like to be 98% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required?
A sample size of n is required.
n is found when M = 0.035. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.035 = 2.327\sqrt{\frac{0.37*0.63}{n}}[/tex]
[tex]0.035\sqrt{n} = 2.327\sqrt{0.37*0.63}[/tex]
[tex]\sqrt{n} = \frac{2.327\sqrt{0.37*0.63}}{0.035}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.37*0.63}}{0.035})^2[/tex]
[tex]n = 1030.4[/tex]
Rounding up:
A sample size of 1031 is required.

The population of leave town is 1-23,560 and is decreasing at a rate of 1.5%
each
year.
a) when will the population of Leavetown drop below 47,000 Cto the nearest
year)?
b) what will the population of leavetown be years from now?
Answer: a is correct
Step-by-step explanation:
At 25 years
Step-by-step explanation:
123,000 x 2.375% = 2,921.25. This gives you the rate that the population is decreasing. How long will it take to get to 50,000. Do reverse operations to find this answer: 123,000 - 50,000 = 73,000, the population need to decrease by 73,000 to get to 50,000. So let's multiply our rate of 2,921.25 x 25 = 73,031 and our final step.. 123,000 - 73,031 = 49,969 below 50,000

What is the m angle3 ?
The measure of m<3 is 105 degrees
Using the law that states that the sum of an interior angle of a rectangle is equal to the exterior.
From the given diagram;
m<X + m<Y = m<3
Given that m<X= 55 degrees and m<Y = 50 degrees
m<3 = 55 + 50
m<3 = 105 degrees
Hence the measure of m<3 is 105 degrees

The first 5 terms in a pattern are
shown below.
25 13 27
-6,-4' 2' 4-7
If the pattern continues, which
equatior. could be used to find the nth
term?
Answer:
Option B. m(n) = –5.75 –¼n
Step-by-step explanation:
The sequence is given below:
–6, –25/4, –13/2, –27/4, –7
Next, we shall determine the common difference.
Common difference (d) = 2nd – First
2nd term = –25/4
First term = –6
d = –25/4 – – 6
d = –25/4 + 6
d = –6.25 + 6
d = –0.25 = –¼
Finally, we shall determine the nth term
Tₙ = a + (n –1)d
First term (a) = –6
Common difference (d) = –¼
Tₙ = a + (n –1)d
Tₙ = –6 + (n –1)–¼
Tₙ = –6 –¼n + ¼
Tₙ = –6 + ¼ –¼n
Tₙ = –6 + 0.25 –¼n
Tₙ = –5.75 –¼n
Thus, the nth term is given by:
m(n) = –5.75 –¼n

Based on these results, express the probability that the next person will purchase no
more than one costume as a fraction in simplest form.
Answer: 49/50

Challenge A bag contains pennies, nickels dimes, and quarters. There are 50 coins in all of the
coins 18% are pennies and 40% are dimes. There are 2 more nickels than pennies. How much
money does the bag contain
The bag contains S
Answer:
The bag contains $5.14
Step-by-step explanation:
18% of 50 = (.18)(50) = 9 pennies
40% of 50 = (.40)(50) = 20 dimes
2 more nickels than pennies = 9 + 2 = 11 nickels
40 coins so far, so 50 - 40 = 10 quarters
Total value:
9 x ($0.01) = $0.09 for pennies
20 x ($0.10) = $2.00 for dimes
11 x ($0.05) = $0.55 for nickels
10 x ($0.25) = $2.50 for quarters
Grand total value = $5.14

Is a triangle with the side lengths 4 feet, 7.5 feet, and 8.5 feet a right triangle? Why or why not?
Answer: Yes, it is a right triangle
Step-by-step explanation:
Use the pythagorean theorem in order to determine whether this triangle is a right triangle. Plug in the values given in the problem (4, 7.5, and 8.5) into this equation (a^2+b^2=c^2). This gives you 4^2+7.5^2=8.5^2, and this equation is valid because 4^2+7.5^2 does equal 8.5^2.
Answer:
Yes, because 4^2+7.5^2=8.5^2.

Solve for xxx in the diagram below
Answer:
x=20°
Step-by-step explanation:
x° + 100° + 3x° = 180° => 4x°+100°=180° => 4x=180°-100°=80° => x=80° : 4 = 20° => x=20°
The value of angle x will be equal to 20°.
What is a supplementary angle?If two angles sum up to 180 degrees, they are referred to as supplementary angles. A straight angle is created by supplementary angles (180 degrees)
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that the three angles are x, 3x, and 100 degrees. The value of the angle x will be calculated as below:-
For supplementary angles, the sum of the angles is 180 degrees.
x° + 100° + 3x° = 180°
4x°+100°=180°
4x=180°-100°=80°
x=80° : 4
x=20°
Therefore, the value of angle x will be equal to 20°.
