6- If, in a sample of n=16 selected from a normal population,x̅=56 and S=12, what is the value of the t-test statistic if you are testing the null hypothesis, H0: µ=50?

Question

1-   If, in a sample of n=16 selected from a normal population,x̅=56 and S=12, what is the value of the t-test statistic if you are testing the null hypothesis, H₀: µ=50?

Answer 1

t = (xbar - mu)/(S/sqrt(n)) = (56-50)/(12/sqrt(16)) = 6/3 = 2
