- Suppose a company charges a premium of $150 per year for an insurance policy for storm damage to roofs. Actuarial studies show that in case of a storm, the insurance company will pay out an average of $8000 for damage to a composition shingle roof and an average of $12,000 for damage to a shake roof. They also determine that out of every 10,000 policies, there are 7 claims per year made on composition shingle roofs and 11 claims per year made on shake roofs. What is the company’s expected value (i.e., expected profit) per year of a storm insurance policy? What annual profit can the company expect if it issues 1000 such policies? Determine the probability of a composition shingle roof claim out of 10,000 = ______ Determine the probability of a shake roof claim out of 10,000 = ______ How many claims are made out of 10,000? = _______ What is the probability of no claims out of 10,000? = _______ How much does each shingle roof claim cost the company, don’t forget each person pays $150…In 3b where did you get the yp=(a + bx) fromThe management of the local zoo wants to know if all of their animal exhibits are equally popular. If there is significant evidence that some of the exhibits are not being visited frequently enough, then changes may need to take place within the zoo. A tally of visitors is taken for each of the following animals throughout the course of a week, and the results are contained in the following table. At α=0.05, determine whether there is sufficient evidence to conclude that some exhibits are less popular than others.

The marketing department is planning todemonstrate this calculator to a group of potential customers, but it is worried about someinitial problems, which have resulted in 4 percent of the new calculators developingmathematical inconsistencies. The marketing VP is planning on randomly selecting a groupof calculators for this demonstration and is worried about the chances of selecting acalculator that could start malfunctioning. He believes that whether or not a calculatormalfunctions is a Bernoulli process, and he is convinced that the probability of a malfunctionis really about 0.04. Assuming that the VP selects exactly 50 calculators to use in thedemonstration, and using the Poisson distribution as an approximation of the binomial whatis the chance of getting at least two calculators malfunctioning?The manufacturer of large liquid crystal display (LCD) is difficult.
