Explanation / Answer

5. Suppose that the probability that any stock increases in price (over a 3 month period of time) is 60%. What is the probability that in a sample of 145 stocks that you buy that less than 55% increase in price (over a 3 month period of time)? (please round your answer to 4 decimal places)

P( z < 0.55 - 0.60 / ( srqt 0.60*0.40 / 145 ) )

P( z < -1.23 ) = 0.1093
