- \( \alpha=0.05 \) (significance level)

What is the test statistic (z-score) of this one-mean hypothesis test?

Select the correct answer below:
\( \frac{7}{\frac{18}{\sqrt{22}}} \approx 1.82 \)
\( \frac{7}{\frac{18}{\sqrt{25}}} \approx 1.87 \)
\( \frac{h^{7}}{\frac{18}{\sqrt{2}}} \approx-1.82 \)

- H0: μ=150 ; Ha: μ≠ 150
- α=0.05 (significance level)

What is the test statistic (z-score) of this one-mean hypothesis test?

Select the correct answer below:
(7)/((18)/(√(22)))≈ 1.82
(7)/((18)/(√(25)))≈ 1.87
(h^7)/((18)/(√(2)))≈-1.82
(-7)/((1 x)/(25))≈-1.87
