A researcher randomly sampled 30 graduates of an MBA program and recorded data about their starting salaries. Of primary interest to the researcher is whether starting salaries differ based on gender. The researcher performs apooled-variance t-test of the mean salaries of the females (Population 1) and males (Population 2) in the sample. Assume α = 0.10. If the p-value = 0.1898 and a two-tail test is conducted, what is the proper interpretation for the decision of this test? A There...

You are a researcher that wants to test whether exercising for 20 mins per day affects happiness. You have a database for students with mean happiness of 65 and SD of 13. You know that the database is normally distributed and conduct an experiment which you have 5 students exercise 20mins/day for 7days. After the last day they rate their happiness on a scale of 1-100 with 1 being extremely unhappy and 100 indicating extremely happy. Their result as follows...

1. Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the bone density test scores that can be used as cutoff values separating the lowest 6​% and highest 6​%, indicating levels that are too low or too​ high, respectively. 2. Assume that the readings on the thermometers are normally distributed with a mean of 0°...

Question 13 (1 point) A statistics professor wants to examine the number of hours that seniors and freshmen study for the final. Specifically, the professor wants to test if the average number of hours that seniors study is greater than the average number of hours that freshmen study. If the seniors are considered group 1 and the freshmen are considered group 2, what are the hypotheses for this scenario? Question 13 options: 1) HO: μ1 = μ2 HA: μ1 ≠...

1) The value of the z-score that is obtained for a hypothesis test is influenced by several factors. Some factors influence the size of the numerator of the z-score and other factors influence the size of the standard error in the denominator. For each of the following, indicate whether the factor influences the numerator or denominator of the z-score and determine whether the effect would be to increase the value of z (farther from zero) or decrease the value of...
