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: 14 12 13 10 Friday the 13th: What are the hypotheses for this test? Let d be the in the numbers of hospital admissions resulting from motor vehicle crashes for the population of all pairs of data.Explanation / Answer
Solution:-
let d be the mean of the difference in the number of hospital admissions resulting from motor veicle crashes for the population of all pairs of data.
H0: d = 0
H1: d notequal 0
------------------
difference = -5,-7,-2,1,-2,-8
d = 3.8333
sd = 3.4303
t = (3.8333 - 0 )/(3.4303/sqrt(6) = -2.7373
