Use the one-mean t-test to perform the hypothesis test. Use the critical value approach.
x = 3.1, s= 0.52, n= 9, H0: = 2.85, Ha: > 2.85, a= 0.01
a) Test statistic: t= 1.44. Critical value: t= 2.821. Do not reject H0.
b) Test statistic: t= 1.44. Critical value: t= 2.896. Reject H0.
c) Test statistic: t= 1.44. Critical value: t= 2.33. Do nor reject H0.
d) Test statistic: t= 1.44. Critical value: t= 2.896. Do not reject H0.
