Assume that the significance level is alpha equals 0.01. use the given information to find the p-value and the critical value(s). with upper h 1 : p not equals three fourths , the test statistic is zequalsnegative 1.64.

 0.1010052

Step-by-step explanation:

Given : Significance level :

Alternative hypothesis :

The test statistic value :

Since , the alternative hypothesis is two-tailed, so the test is a two-tailed test.

Using standard normal distribution table for z, we have

The P-value of two-tailed test will be :-

Hence, the P-value = 0.1010052
