please show with the solution

You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 60%. With Ha : p 60% you obtain a test statistic of z=2.503z=2.503. Find the p-value accurate to 4 decimal places.

p-value =

You are conducting a study to see if the probability of catching the flu this year is significantly less than 0.28. Thus you are performing a left-tailed test. Your sample data produce the test statistic z=2.414z=-2.414. Find the p-value accurate to 4 decimal places.

p-value =

Explanation / Answer

We use the Z tables to solve the problem.

Here with attached is link of the Z tables I refer, you may use the same:

a. z = 2.503 has a p-value of 1-.9939 = .0062

Sameway, we solve the 2nd part:

b. z = -2.414 has a p-value of .0080
