Compute the linear correlation coefficient between the two variables and determine whether a linear relation exists.The table shows the number of days off last year and the earnings for the year (in thousands of dollars) for nine randomly selected insurance salesmen. Number of Days Off vs Yearly Earnings Number of Days off, x 3 6 9 7 12 5 18 11 8 Yearly Earnings (thousands), y 91 79 73 75 64 85 48 69 75  

Provide an appropriate response.An insurance actuary asked a sample of senior citizens the cause of their automobile accidents over a two-year period. The random variable x represents the number of accidents caused by their failure to yield the right of way. a) Use the frequency distribution to construct a probability distribution. Accidents Senior Citizens Relative Frequency 0 5 [relfreq0] 1 3 [relfreq1] 2 9 [relfreq2] 3 4 [relfreq3] 4 3 [relfreq4] 5 1 [relfreq5] b) Is it unusual for a senior citizen to have 5 accidents when failing to yield the right of way (Y/N)? [unusual]

Provide an appropriate response.A motel has a policy of booking as many as 150 guests in a building that holds 140. Past studies indicate that only 85% of booked guests show up for their room. Find the probability that if the motel books 150 guests, not enough rooms will be available.

Provide an appropriate response.A lab orders a shipment of 100 rats a week, 52 weeks a year, from a rat supplier for experiments that the lab conducts. Prices for each weekly shipment of rats follow the distribution below: Prices for Shipments of Lab Rats Price $10.00 $12.50 $15.00 Probability 0.30 0.15 0.55 How much should the lab budget for next year’s rat orders assuming this distribution does not change. (Hint: find the expected price.)

Provide an appropriate response.A 28-year-old man pays $175 for a one-year life insurance policy with coverage of $130,000. If the probability that he will live through the year is 0.9994, what is the expected value for the insurance policy to the insurance company?

Solve the problem.A certain disease only affects men 20 years of age or older. The chart shows the probability that a man with the disease falls in the given age group.
