Extracted text: Investigation Background: For this investigation you will be comparing the Exam 1 scores between two populations. 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. Based on the P-value that you obtained in part d of section 3, do you reject or fail to reject the null hypothesis? Explain your reasoning. a. b. In the context of the investigation, interpret your answer from section 4 part a.
