A sample mean, sample standard deviation, and sample size are given. Perform the required hypothesis test about the mean, , of the normal population from which the sample was drawn.
H0:=132,Ha:132,
x=137, s = 14.2,n=25, = 0.10
Test statistic: t=1.76. Critical values: t=1.711. RejectH0. There issufficient evidence to conclude that the mean is different from 132.
Test statistic: t=1.76. Critical values: t=1.711. Do not rejectH0. There is not sufficient evidence to conclude that the mean is different from 132.
Test statistic: t=1.76. Critical values: t=1.645. Do not rejectH0. There is not sufficient evidence to conclude that the mean is different from 132.
Test statistic: t=1.57. Critical values: t=1.645. Do not rejectH0. There is not sufficient evidence to conclude that the mean is different from 132.
