Suppose a random sample of size 15 is taken from a normal population with mean 25 and standard deviation 5; and a second, independent random sample of size 21 is taken from a normal population with mean 10 and standard deviation 4. Find the probability P(X- X2 2 17). (Use Appendix Table 3.

A common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight. Suppose that the percentage of no-shows at flight time is 2%. For a particular flight with 170 seats, a total of 175 tickets were sold. What is the probability that the airline overbooked this flight? Click here to view page 1 of the standard normal...
A random sample of 20 chocolate energy bars of a certain brand has, on average, 210 calories per bar, with a standard deviation of 15 calories. Construct a 99% confidence interval for the true mean calorie content of this brand of energy bar. Assume that the distribution of the calorie content is approximately normal.

Question 3 (9 marks) Consider the following information about a non-dividend paying stock: The current stock price is $36, and its return standard deviation is 30% per year. The continuous compound risk-free rate is 3% per year. Assume that the Black-Scholes model correctly prices all the options written on the stock given the information above. a). A call option written on the stock expires in 1 year and has an exercise price of $36. Calculate the Black-Scholes value of the...
