Assume that the significance level is 001 Use the given info

Assume that the significance level is ?=0.01. Use the given information to find the P-value and the critical value(s).The test statistic of?

z=1.64 is obtained when testing the claim that p>0.9.

A).      THE P-value=____?

(Round to four decimal places as needed.)

B.)    The critical value Z=_____

(Round to four decimal places as needed.)

Solution

(A) It is a righ-tailed test.

So the p-value= P(Z>1.64) = 0.0505 (from standard normal table)

(B) Given ?=0.01, the critical value is Z(0.01) = 2.3263 (from standard normal table)
