Question
In a memory test, the test subjects are shown 400 objects and are asked after two hours to name the objects. The historical records show that test subjects remember 80% of the objects after two hours. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of \(\hat{p}\), where \(\hat{p}\) is the proportion of objects that are remembered by a test subject. [ ] (b) Find the standard deviation of \(\hat{p}\). [ ] (c) Compute an approximation for \(P(\hat{p} < 0.82)\), which is the probability that fewer than 82% of the objects are remembered by a test subject. Round your answer to four decimal places. [ ]
