You are testing H0 100 against Ha 100 based on an SRS of 9

You are testing H₀: = 100 against H_a: < 100 based on an SRS of 9 observations from a Normal population. The data give x = 98 and s = 3. The value of the t statistic is

A. -2

B. -98

C. -6

Solution

the formula for the value of T statistic

T = xbar - miu / [s / srqt ( n)]

T = 98 - 100 / [ 3 / srqt (9) ]

T = -2
