Normal distribution
The execution times in seconds of a certain experiment have a
normal distribution with a mean of 38 and a variance of 36.
a) What is the probability that an experiment test will last more
than 42 seconds?
b) If the test times located in the top 10% are classified as
reserved, what is the minimum time to be in this category?
c) What is the proportion of tests that have times that exceed at
least five seconds...

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...
