In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities. Do you try to pad an insurance claim to cover your deductible? About 41% of all U.S. adults will try to pad their insurance claims! Suppose that you are the director of an insurance adjustment office. Your office has just received 138 insurance claims to be processed in the next few days. Find the following probabilities. (Round your answers to four decimal places.) (a) half or more of the claims have been padded (b) fewer than 45 of the claims have been padded (c) from 40 to 64 of the claims have been padded (d) more than 80 of the claims have not been padded

Suppose that you are offered the following "deal." You roll a six sided die. If you roll a 6, you win $15. If you roll a 3, 4 or 5, you win $1. Otherwise, you pay $10. a. Complete the PDF Table. List the X values, where X is the profit, from smallest to largest. Round to 4 decimal places where appropriate. Probability Distribution Table X P(X) b. Find the expected profit. $ (Round to the nearest cent) c. Interpret the expected value. This is the most likely amount of money you will win. O If you play many games you will likely lose on average very close to $0.33 per game. O You will win this much if you play a game. d. Based on the expected value, should you play this game? O No, this is a gambling game and it is always a bad idea to gamble. O Yes, since the expected value is positive, you would be very likely to come home with more money if you played many games. O Yes, because you can win $15.00 which is greater than the $10.00 that you can lose. O Yes, since the expected value is 0,…

An insurance company will insure a $75,000 automobile for its full value against theft by apolicy with a premium of $1,500 per year. Suppose that the probability that the automobile willbe stolen is 0.0075.a. Construct the probability distribution.b. Calculate the insurance company's expected net profit for this policy.

Suppose that you are offered the following "deal." You roll a six sided die. If you roll a 6, you win $7. If you roll a 4 or 5, you win $2. Otherwise, you pay $8.a. Complete the PDF Table. List the X values, where X is the profit, from smallest to largest. Round to 4 decimal places where appropriate.  Probability Distribution Table X P(X)             b. Find the expected profit. $ (Round to the nearest cent)c. Interpret the expected value. If you play many games you will likely lose on average very close to $2.17 per game. You will win this much if you play a game. This is the most likely amount of money you will win. d. Based on the expected value, should you play this game? No, since the expected value is negative, you would be very likely to come home with less money if you played many games. Yes, since the expected value is positive, you would be very likely to come home with more money if you played many games. Yes, since the expected value is 0, you would be…
