In your response, be sure to address the following:1.Provide an overview of your exploratory data analysis (EDA) for both pre-test and post-test creativity scores, including descriptive statistics such as mean, median, and standarddeviation.2.Describe the hypotheses you tested in both the paired samples t-test and the independentt-test. What were the results of each test, and how did they influence your conclusionabout the effect of the creative writing course?3.Discuss the assumptions you tested for in both t-tests, particularly focusing on thehomogeneity of variances in the independent t-test. How did the results support youranalysis?4.Reflect on the differences between the two tests (paired samples t-test and independent t-test) and explain why they might have yielded different findings. How would these testsbe used differently in future research or applied studies?Word Count Requirement: 800-1000 words
