Is the Pandemic shaping individuals' desires to have children? Use the class survey to inquire this question, using the following steps. a. Split the sample into two parts: (1) those who are either not at all or moderately worried about climate change, and (2) those who are very or extremely worried about climate change, using answers to Question #16 (Q16) [How worried are you about climate change?]. Calculate the mean and standard deviation of answers to Question #18 (Q18) [How many children do you want to have?] for the two groups separately. According to these sample data, which group reported a higher desired number of children? How large is the difference? b. Calculate a 95% confidence interval for the difference between the mean number of desired children for those who are moderately or not worried about climate change vs those who are very or extremely worried about it. Interpret this confidence interval with words. c. Are the two groups in the population different in terms of desired number of children? Answer this question using a two-sample t test with a=.05. State your conclusion in English. d. Discuss whether the data meet the distributional and sample size requirements for the t procedures you used in Questions 3 & 4.
