The hypothesis test

H0:μ=32H1:μ≠32
is to be carried out. A random sample is selected, and yields x¯=37 and s = 15. If the value of the t statistic is t=1.49071198499986, what is the sample size? (If rounding is required, round to the nearest integer.)

Answer #1

T test for single mean

Substitute here known values and solve for n

square on both sides

=>n=20.01

Therefore, sample size approximately will be 20
