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, 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.
