Question

Exhibit 9-2
n = 64  = 50
s = 16
H 0 : $\mu$ 54
H a : $\mu$ < 54
-Refer to Exhibit 9-2. The test statistic equals
A)-4 
B)-3 
C)-2 
D)-1

Quizplus · Accepted Answer

From the given information, we can calculate the test statistic as
(50-64)/16 = -0.875
Since the calculated test statistic is less than -2, we reject the null hypothesis. Therefore, the best choice is C.

Exhibit 9-2 N = 64 = 50 S = μ\muμ

Exhibit 9-2
N = 64 = 50
S = $\mu$
