Mean Comparison with 95% Cls of Two Sample Means Two student political organizations are having a dispute about the popularity of President Biden. The College Democrats argue that Biden is more unpopular with people age 18-29 than those people who are 30 years of age or older. The College Republicans disagree, arguing that younger people (Age 18-29) are no different from older people (those age 30 or older), meaning that Biden's approval rating among the younger age group is not different from that of the older age group. In order to resolve the dispute, use the following data from a random survey of individuals, to calculate 95% confidence intervals of the sample mean Biden approval for the younger and older groups: . Biden approval rating (0 - 100) - Sample mean Biden approval rating for the younger age group = 37 (standard deviation = 21, sample size = 400) - Sample mean Biden approval rating for the older age group = 42 (standard deviation = 45, sample size = 1,600) Calculate the standard error of the sample mean for the younger group (two decimal places):|:| Calculate the standard error of the sample mean for the older group (two decimal places): |:| For the younger group, calculate the lower bound of the 95% confidence interval of the sample mean Biden approval rating [two decimal places]: |:| For the younger group, calculate the upper bound of the 95% Confidence Interval of the sample mean Biden approval rating [two decimal places]: |:| For the older group, calculate the lower bound of the 95% confidence interval of the sample mean Biden approval rating [two decimal places]: |:| For the older group, calculate the upper bound of the 95% Confidence Interval of the sample mean Biden approval rating [two decimal places]: |:| Based on your calculation of the two 95% confidence intervals, which group is most likely correct, College Democrats or College Republicans? OCollege Democrats OCollege Republicans OBoth are Wrong ONot enough evidence to say Explanation Mean Comparison Biden Approval Rating Explain the reasoning for your answer to the question above by referring to the appropriate statistical evidence
