![4. 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.

In this example, Ha 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.

(Round to two decimal places as needed.)
Based on the confidence interval, can one reject 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?
O A. No, because the confidence interval includes zero.
O B. Yes, because the confidence interval does not include zero.
OC. Yes, because the confidence interval includes zero.
O D. No, because the confidence interval does not include zero.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F49a24ce3-a3ec-4450-92e6-12fcfc554e0e%2F268955db-f606-43b2-b61e-bf0fc5ed1221%2Ffu3clmv_processed.png&w=3840&q=75)
