1. The life time of a certain brand of bulbs produced by a company is normally distributed, with mean 210 hours and standard deviation 56 hours. What is the probability that a bulb picked at random from this company’s products will have a life time of: (i) at least 300 hours, (ii) at most 100 hours, (iii) between 150 and 250 hours.

Given the following failure time data in hours: {50, 65, 78, 92, 99, 107, 120, 190, 200, 205}. Assume that the system under study follows an exponential failure distribution. The system under study has a 50 hour warranty. What is the probability that a system in the field will fail during the warranty period?

Question-2 Academic Toys has developed a brand new product line—a series of Business Professor Action Figures (BPAFs) featuring likenesses of popular professors at the local business school. Management needs to decide how to market the dolls. One option is to immediately ramp up production and simultaneously launch an ad campaign in the Academic newspaper. This option would cost $1,000. Based on past experience, new action figures either take off and do well or fail miserably. Hence, the prediction is for...
