Question

Use the calculator displays to the right to make a decision to reject or fail to reject the null hypothesis at a significance level of

α=0.05.

Z-Test		Z-Test
	Inpt: Data	Stats			μ≠40
	μ0:40			z=−2.10818511
	σ:5.25			p=0.03501498
	x:38.25			x=38.25
	n:40			n=40
	μ:	≠μ0	<μ0	>μ0
	Calculate Draw

Choose the correct answer below.

Since the P-value is

less

than

α,

reject

the null hypothesis.

Since the P-value is

less

than

α,

fail to reject

the null hypothesis.

Since the P-value is

greater

than

α,

fail to reject

the null hypothesis.

Since the P-value is

greater

than

α,

reject

the null hypothesis.

Expert Solution

Step 1

From the given information, test statistic value is z = -2.10818511

P-value = 0.03501498.

Level of significance

Population standard deviation value is 5.25.
