What is the sampling method used?From the question, we see that the surveyor selects the twentieth student who enters the building.
Now, the student do not enter the building to be surveyed but instead for other reasons and as such the researcher takes advantage of that and selects them. This is a form of convenience sampling.
It is also a form of systematic sampling because the researcher selects every twentieth student and not any other.
Lastly, it is a form of Voluntary sampling because the students selected to participate in the survey are free to choose whether to participate in the survey or not.

Cooper went into the grocery store at 4:40 p.m. he left the store at 5:13 p.m. how long was cooper inside the grocery store?
Answer:
33 minutes
Explanation:
So, Copper went into the store at 4:40 p.m. then came out at 5:13 p.m.
One way to visualize this is to first count the minutes to 5:00 p.m. and then add the minutes after that. So, there is 20 minutes till 5:00 p.m., and then 13 minutes until 5:13 p.m. 20 + 13 = 33 minutes. This makes it easier to see how long Copper took in the store.

Lisa has collected data to find that the number of pages per book on a book shelf has a normal distribution. what is the probability that a randomly selected book has fewer than 141 pages if the mean is 193 pages and the standard deviation is 26 pages? use the empirical rule. enter your answer as a percent rounded to two decimal places if necessary.
Rounding to two decimal places, the probability that a randomly chosen book contains fewer than 141 pages is about 2.5%.
What amount of money has Lisa amassed in the past six months that is 15% greater than 1,250?If you tell us that you have saved 15% of your income plus $1,250, we must first divide that amount by 15% to arrive at 187.5, and then we must add that figure to $1,250 to arrive at 1,437, which is Lisa's money.
In this issue, our goal is to determine the likelihood that a randomly chosen book contains fewer than 141 pages.
Where x is the value we're interested in (141 pages), is the mean (193 pages), and is the standard deviation, we get the equation z = (x - ) /. z = (141 - 193) / 26 = -2
The z-score informs us of how many standard deviations our value deviates from the mean. 141 pages in this case are two standard deviations away from the mean.
We may estimate that 95% of the data falls within two standard deviations of the mean using the empirical method. We can estimate that P(X 141) 2.5% is the likelihood of choosing a book with fewer than 141 pages.

In triangle $abc,$ angle bisectors $\overline{ad},$ $\overline{be},$ and $\overline{cf}$ meet at $i.$ if $di = 3,$ $bd = 4,$ and $bi = 5,$ then compute the area of triangle $abc.$
∆BDI is necessarily a right triangle, since the squares of the two smaller sides is exactly the square of the longest side.
3² + 4² = 9 + 16 = 25 = 5²
Then the angle bisector AD forms a right angle with the base BC - this means AD is an altitude of ∆ABC.
Since AD bisects the angle at vertex A, we further know that ∆ABC is isosceles, since both ∆ABD and ∆ACD are right triangles with the same height AD. Then the length of BC is twice the length of BD, and ∆ABC has a base of length 8.
Let θ be the measure of one of the base angles of ∆ABC (angle ABC, for instance). Then in ∆BDI, we have the trigonometric relationship
tan(θ/2) = 3/4
from which we get
θ/2 = arctan(3/4)
θ = 2 arctan(3/4) ≈ 73.74°
Then the height of ∆ABC is
tan(θ) = AD/4
AD = 4 tan(θ)
AD = 4 tan(2 arctan(3/4))
AD = 4 • 2 tan(arctan(3/4)) / (1 - tan²(arctan(3/4)))
AD = 4 • 2 • 3/4 / (1 - 9/16) = 96/7
Then the area of ∆ABC is
1/2 • 8 • 96/7 = 384/7

Answer: The answer would be 5%
Explanation:
The closest answer choice is 2.5%, which is the closest value to 1.7% given in the answer choices.
What is z-score?The Z-score is a statistical measure that describes the relationship of a value to the mean of a group of values.
To solve this problem, we can use the standard normal distribution and the z-score formula:
z = (x - μ) / σ
Where x is the value we want to find the probability for, μ is the mean of the distribution, and σ is the standard deviation of the distribution.
In this case, we want to find the percentage of snakes that are longer than 16.6 in., which corresponds to a z-score of:
z = (16.6 - 15) / 0.8 = 2.125
Using a standard normal distribution table or calculator, we can find that the percentage of values in the distribution that are greater than a z-score of 2.125 is approximately 1.7%. Therefore, approximately 1.7% of snakes are longer than 16.6 in.
Thus, the probable answer is 2.5%.

From previous experience, the owner of an apple orchard knows that the mean weight of gala apples is 140 grams. there has been more precipitation than usual this year. the owner believes the weights of the apples will be heavier than usual and therefore the crop will be more profitable. this will allow the owner to expand the orchard. the owner takes a random sample of 30 apples and records their mean weight. what is the consequence of a type i error in this situation?
The consequence of a type I error in this situation is that the owner believes the crop will be more profitable and expands the apple orchard.
What is a type I error?
A type I error can be defined as a type of error that occurs when the null hypothesis is rejected, even though it's actually true.
This ultimately implies that, a type I error concludes that a given result is statistically significant, whereas, in reality, it was due to luck, chance or other unrelated factors.
