Assume that the significance level is alpha 01 Use the given

Assume that the significance level is (alpha) =0.1. Use the given information to find the P-value and the critical value(s).

The test statistic of z=1.87 is obtained when testing the claim that p > 0.3.

Find the P Value and the critical value

Solution

WE will assume that the significance level is a = 0.1. Use the given information to find the P-value and the critical value(s).The test statistic of z=1.87 is obtained when testing the claim that p>0.3.
----
Since the altenate hypothesis is p > 0.3, you have a right-tail test.
------
Since the z-value for p = 0.3 is z = 1.87,

P value = P(z > 1.87) = normalcdf(1.87,100) = 0.0983
----------------------------------------
The critical value is z = invNorm(0.99) = 2.3263
