Chapter 7, Problem 66CE

The price of shares of Bank of Florida at the end of trading each day for the last year followed the normal distribution. Assume there were 240 trading days in the year. The mean price was $42.00 per share and the standard deviation was $2.25 per share.

  1. a. What is the probability that the end-of-day trading price is over $45.00? Estimate the number of days in a year when the trading price finished above $45.00.
  2. b. What percent of the days was the price between $38.00 and $40.00?
  3. c. What is the minimum share price for the top 15% of end-of-day trading prices?
