Question

The test statistic of z equals = 2.37 2.37 is obtained when testing the claim that p greater than > 0.1 0.1. a. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. b. Find the​ P-value. c. Using a significance level of alpha α equals = 0.10 0.10​, should we reject Upper H 0 H0 or should we fail to reject Upper H 0 H0​?

Answer 1

Right tailed, 0.0089, reject.

Explanation:

Given that The test statistic of z equals = 2.37 is obtained when testing the claim that p greater than > 0.1

we see that whenever claim is > it is right tailed. And whenever p <alpha we reject H0

a) Since claim is p>0.1 this is right tailed test.

b) For z =2.37 p value is
`0.5-0.4911\\0.0089`

c)Since p < 0.01 our lapha we reject null hypothesis
