In a memory test, the test subjects are given a large number and are asked to memorize it. Historical records show that 80% of test subjects pass thetest. To pass the test, a subject must exactly repeat all the digits in the number after two hours.A random sample of 625 people to take the memory test is going to be chosen. Let p be the proportion of people in the sample who pass the test.Answer the following. (If necessary, consult a list of formulas.)(a) Find the mean of p.0(b) Find the standard deviation of p0(c) Compute an approximation for P(p<0.84), which is the probability that fewer than 84% of the people in thesample pass the test. Round your answer to four decimal places.ContinueODEC16101WMacBook AirⒸ2022 McGraw Hill LLC. All Rights Reserved. Terms of UsezoomXSubmit AssignmentPrivacy Center5=Accessibility18-CH
