Question

Researchers collected data on the numbers of hospital admissions resulting from motor vehicle crashes, and results are given below for Fridays on the 6th of a month and Fridays on the following 13th of the same month. Use a 0.05 significance level 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. Friday the 6th: Friday the 13th: 10 14 712 12 13 14 11 5 14 What are the hypotheses for this test?

Explanation / Answer

From the given data

Let Mu(d) be the difference in numbers of hospital admissions resulting from vehicle crashes

As p-value is less than the significance level of 0.05, we reject null hypothesis

This means there are significant evidence that the difference in two numbers of two days is not equal to zero.
