A researcher wanted to test the theory that people who live in urban environments are more liberal compared to people who live in suburban environments. To test this, they gave a group of people from the suburbs and a group of people from the city a measure of liberalness (the higher the score, the more liberal-minded you are). The data are given below.

Suburban: ?=15, n=60, ?$ = 3.81 $# Urban: ?=20, n=60, ?$ = 3.39

Run the appropriate hypothesis test (all 4 steps) to test the hypothesis people in urban and suburban environments have significantly different levels of liberalness. Use an alpha of α=0.01, two-tailed test. (Use the back of your sheet to complete this problem). Are you surprised at all with your results? Why/Why not?

Jenny wanted to know if people who exercise regularly eat more apples than people who don’t exercise regularly. She took a simple random sample of six people who exercise. Their standard deviation was 2.00. She then took a new simple random sample of eight people who don’t exercise. Their standard deviation was 1.51. Please calculate the test statistic for this experiment; then state the critical value; then come to a conclusion concerning the null hypothesis; and then state what the...

A researcher would like to test whether or not people who have stocked up on a year’s supply of toilet paper are experiencing less stress during a statewide stay-at-home order. A statewide poll indicates that the average stress level for the general state population is 60.5 (with a standard deviation of 11.6) and is normally distributed. Using a random sample of 36 toilet paper hoarders that have a mean stress level of 54.7 (and a standard deviation of 10.3), test...

As a researcher, you are curious if people who eat vitamins have more energy. To assess this question, you will calculate a confidence interval for the following data. The average energy on a scale of 1-20 in the general population is μ (mu) = 13, with σ (sigma) = 3.5. You recruit 36 people who eat vitamins and assess their energy. This sample has an average of xbar = 14. a. State the null and alternative hypotheses. b. Find the...
