Question

You are testing H0: μ = 100 against Ha: μ < 100 based on an SRS of 21 observations from a Normal population. The data give x̄ = 9.1 and s = 3.6.

The value of the t statistic (±0.01) is _______

Answer 1

Answer #1

Solution :

Test statistic = t

= ( - ) / s / n

= (9.1 - 100) / 3.6 / 21

= -115.71

t = -115.71
