A: In this example, ud is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the number of hospital admissions on Friday the 6th minus the number of hospital admissions on Friday the 13th. Find the 95% confidence interval.

Please answer parts A & B, the data table is in the picture below. Thank you! :)
Data on the numbers of hospital admissions resulting from motor vehicle crashes are given below for Fridays on the 6th of a month and Fridays on the following 13th of the same month. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Construct a 95% confidence interval estimate of the mean of the population of differences between hospital admissions. Use the confidence interval to test the claim that when the 13th day of a month falls on a? Friday, the numbers of hospital admissions from motor vehicle crashes are not affected. Data Table in picture below: A: In this example, ud is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the number of hospital admissions on Friday the 6th minus the number of hospital admissions on Friday the 13th. Find the 95% confidence interval. <ud< B: Based on the confidence interval, can one reject the claim that when the 13th day of the month falls on a Friday, the numbers of hospital admissions from motor vehicle crashes are not affected? Option A: Yes, because the confidence interval includes zero Option B: No, because the confidence interval does not include zero. Option C: No, because the confidence interval includes zero Option D: Yes, because the confidence interval does not include zero.
