Answer:

The test statistic (z-score) of this one-mean hypothesis test is z=1.823.

Step-by-step explanation:

The null and alternative hypothesis are:

H_0: \mu=150\\\\H_a: \mu\neq 150

The significance level is 0.05.

The sample size is n=22.

The sample mean is M=157.

The standard deviation is 18.

The z-score can be calculated as:

z=\frac{M-\mu}{\sigma/\sqrt{n}}=\frac{157-150}{18/\sqrt{22}}  =\frac{7}{3.84} =1.823

The test statistic (z-score) of this one-mean hypothesis test is z=1.823.
