In a memory test, the test subjects are shown 300 objects and are asked after two hours to name the objects. The historical records show that test subjects remember 75% of the objects after two hours. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p is the proportion of objects that are remembered by a test subject. .75 (b) Find the standard deviation of p. (c) Compute an approximation for P(p<0.76), which is the probability that fewer than 76% of the objects are remembered by a test subject. Round your answer to four decimal places.
