In a symmetric single-peak distribution, if the bonus is less than the 20th percentile, the first quadrant is placed and the bonus is greater than the 80th percentile, the third quadrant is placed, which is the midpoint of the quadrant.
The results of a state mathematics test for random samples of students taught by two different teachers at the same school are shown below. Can you conclude there is a difference in the mean mathematics test scores for the students of the two teachers? Teacher 1 Teacher 2 xbar = 473 xbar = 459 S1= 39.7 S2 = 24.5 n1 = 8 n2 = 18 Identify the rejection region (critical region) and fail to reject region. Show this by drawing a curve and separate the rejection region from the fail to reject region using critical values.

A researcher asks a sample of people about their attitudes toward marijuana legalization and concludes people have a wide variety of opinions, and are equally likely to be anywhere between strongly in favor of it to strongly opposed to it. She reaches this conclusion because the shape of the distribution is

In an industrial setting, process steam has been found to be normally distributed with an average value of 25,000 pounds per hour. There is an 80% probability that steam flow lies between 20,000 and 30,000 pounds per hour. What is the variance of the steam flow?
A scrap metal dealer claims that the mean of his cash sales is 'no more than R80', but an Internal Revenue Service agent believes the dealer is untruthful. The agent randomly selects a sample of 20 cash customers and find the mean purchase to be R91, with a variance of R441. The agent's correct alternative hypothesis is:
