Question Answered step-by-step Use the information in the scenarios to complete the hypothesis… Use the information in the scenarios to complete the hypothesis testing process. Your final answerfor each scenario should include all four parts of Step 6 of the hypothesis testing process. 1. Dr. Skiba was an administrator for the Vincent Consolidated School System. He wanted to assesswhether the system’s rural students had a higher rate of absenteeism than the population of students inthe school system. To research this question, he selected a random sample of 80 students living in ruralareas. The students in the sample were absent an average of 4.63 days (s = 1.17) during the last schoolyear. Dr. Skiba knew that the average number of absentee days for all the students was 3.79. Do ruralstudents have a higher number of absences than the population of students? Use alpha = .05; ifappropriate, calculate a 95% confidence interval and an effect size (use Cohen’s d).2.  Professor O’Meara wanted to assess whether the average age of psychology students was statisticallylower = from the average age of all students in the College of Science and Health (CSH). Toinvestigate, she selected a random sample of 100 psychology students. The sample had an average ageof 20.57 years (s = 2.09). Based on university records, Professor O’Meara knew that the average age ofall CSH students was 23.94 years. Is the average age of psychology students lower than the average ageof all CSH students? Use alpha = .05; if appropriate, calculate a 95% confidence interval and an effectsize (use r2).SQ2022 Math Statistics and Probability PSY 240 Share QuestionEmailCopy link Comments (0)
