Please include t- value P- value Critical t values
Thank you for helping me study 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: 9 14 5 12 12 1411 4 6 12 14 What are the hypotheses for this test? 1 in the numbers of hospital admissions resulting from motor Let H be the vehicle crashes for the population of all pairs of data.

Explanation / Answer
Ho: There is no significant difference in mean motor vehicle crash between Friday on 6th and 13th.
H1: There is a significant difference in mean motor vehicle crash between Friday on 6th and 13th.
difference between Friday on 6th and 13th is Ud:
Ho: mu=0
H1: mu=! 0
pair t-test,
t=2.7373
critical value=2.571
p=0.04092.
the result is significant at p<0.05
hence, reject the null hypothesis as p-value is significant.
and there is a significant difference in mean motor vehicle crash between Friday on 6th and 13th.
therefore, They claim wrong.
