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>p0.61, which is the
probability that more than 61% of the stocks that went up yesterday
will go up again today. Round your answer to four decimal
places.
