People end up tossing 12% of what they buy at the grocery store (Reader'sDigest, March 2009). Assume this is the true population proportion and thatyou plan to take a sample survey of 540 grocery shoppers to furtherinvestigate their behavior. Answer questions 8-10. The expected value and standard error of the proportion of groceries thrownout by your sample respondents areE(p) = 0.88; op = 0.1056.E(p) = 0.88; oi0.014.E(F) = 0.12; op = 0.014.E(p) = 0.12; 0p= 0.000196.

Here, proportion is 12% , ( 0.12). Sample is 540. We will use standard error for proportion.

Empirical research on stock market data for two consecutive trading days indicates that 60% of the stocks that went up on the first day also went up on the second day. Yesterday, 600 stocks went up. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p gives the proportion of the 600 stocks that went up yesterday that will go up today. (b) Find the standard deviation of p. (c) Compute an approximation for P(p <0.58), which is the probability that fewer than 58% of the stocks that went up yesterday will go up again today. Round your answer to four decimal places.
