A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use the critical-value approach.

a: μ ≠ 32.6, α = 0.05.
◦ Test statistic: t = 4.95. Critical values:
Reject
There is sufficient evidence to support the claim that the mean is different from 32.6.
◦ Test statistic: t = 4.95. Critical values:
Reject
There is sufficient evidence to support the claim that the mean is different from 32.6.
◦ Test statistic: t = 4.95. Critical values:
Do not reject
There is not sufficient evidence to support the claim that the mean is different from 32.6.
◦ Test statistic: t = 4.95. Critical values:
Do not reject
There is not sufficient evidence to support the claim that the mean is different from 32.6.
