Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. C. Using a significance level of ?-005, should we reject Ho or should we fail to reject Ho?

P-value Round to three decimal places as needed.)

Explanation / Answer

a)

The test is two tailed.

b)

The p-value is

p-value = 2 [1 - P(z <= 1.14) ] = 2 * [1 - 0.8729] = 0.2542

c)

Since p-value is greater than 0.05 so we fail to reject the null hypothesis.
