Please help! Will mark brainliest. The answer is 1.96 but I need to know to they got the answer. Determine the critical value Z to test the claim about the population proportion p not equal to 0.325 given n=42 and p hat=0.247. Use alpha=0.05

Here we are looking to find the critical value Z.

When alpha is 0.05:

0.05/2=.025

Using your z chart this would equal 1.96 positive or negative. Hope this helps!
