(((((((((((9)))))))

Assume that the significance level is ?=0.1. Use the given statement and find the P-value and critical value(s).The test statistic of z=?1.10?

is obtained when testing the claim that p=14.

The P-value= _____

(Round to four decimal places as needed.)

The critical value Z=______

(Round to four decimal places as needed.)

Solution

It is a two-tailed test.

So the p-value= 2*P(Z<?1.10) =0.2713 (from standard normal table)

Given ?=0.1, the critical values are Z(0.05) =-1.6449 or 1.6449(from standard normal table)
