The first population will be students from all of my sections from my Fall 2020 Math 140 class. The second population will be students from all of my sections from my Spring 2021 Math140 class. The data set you are provided with contains two columns. The first column, Fall2020_Score, contains the Exam 1 scores from Fall 2020 Math140-1146. The second column, Spring2021_Score, contains the scores from your class: Spring 2021 Math140-1146. Our goal is to determine whether there is a difference in the mean scores of Exam1 from Fall 2020 and Spring 2021. a. For each sample, include in the report a screenshot of the Summary statistics generated by StatCrunch that is , Mean, Std. Dev., Min, Q1, Median, Q3, Max. b. Write a sentence interpreting the meaning of each number in the five-number summary: Min, Q1, Median, Q3, Max. c. For each sample, create a histogram of the data and include a screenshot of it in your report. Write a sentence describing the shape of the distributions. d. Use StatCrunch to run a hypothesis test to test the claim. What is your test statistic? What is your P-value? Include a screenshot of your results. e. Use StatCrunch to create a 95% Confidence Interval. Write it in interval notation. Include a screenshot of your results.
