Name: Week 7 HSCI 390L: Hypothesis Testing Worksheet 1. It has been reported that the average credit card debt for college seniors is $3262. The student senate at a large university feels that their seniors have a debt much less than this. so they conduct a study of 50 randomly selected seniors and finds that the average debt is $2995, and the population standard deviation is $1100. Let's conduct the test based on an alpha level of 0.05. Complete the...
