![Researchers collected data on the numbers of hospital admissions resulting from motor vehicle crashes. The results are given for Fridays on the 6th of a month and Fridays on the following 13th of the same month. A 0.05 significance level is used 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:
- **Friday the 6th:** 10, 7, 12, 12, 4, 4
- **Friday the 13th:** 14, 13, 15, 11, 6, 11
**Hypothesis Test:**
What are the hypotheses for this test?
- Let \(\mu_d\) be the [mean difference] in the numbers of hospital admissions resulting from motor vehicle crashes for the population of all pairs of data.
- \(H_0: \mu_d = 0\)
- \(H_1: \mu_d \neq 0\)
This test checks if there's a significant difference in hospital admissions between the two specified Fridays.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd2cb18fb-051f-49ed-b2ca-05926664451b%2F868c0855-a422-4c9d-911f-b470c257aef7%2Frsacjt_processed.jpeg&w=3840&q=75)
