Determine the probability of making a Type II error for the following hypothesis test, given that =1025.

H0:=980

H1:>980

For this test, take =54, n=22, and =0.07

Edfinity is requiring the full number without rounding. Previously it was answered with the following formula but that number is not correct.

p(x >1025) = 0.0004

Explanation:

t = (x-)/[/n]

t = (1025-980)/[54/22]

t = 3.909

From t table the value of 3.909 is 0.0004

p(x >1025) = 0.0004
