Based on past experience, a bank believes that 12% of the people who receive loans will not make payments on time. The bank has recently approved 100 loans. Answer the following questions. a) What are the mean and standard deviation of the proportion of clients in this group who may not make timely payments? HP = 0.12 SD p) = 0.032 (Round to three decimal places as needed.) b) What assumptions underlie your model? Are the conditions met? A. With reasonable assumptions about the sample, all the conditions are met. O B. The randomization and success/failure conditions are not met. O C. The success/failure condition is not met. O D. The 10% and success/failure conditions are not met. O E. The randomization condition is not met. O F. The 10% condition is not met. O G. The randomization and 10% conditions are not met. O H. Without unreasonable assumptions, none of the conditions are met. c) What is the probability that over 13% of these clients will not make timely payments? P(p>0.13) = (Round to three decimal places as needed.) Enter your answer in the answer box and then click Check Answer. Clear All All parts showing 31566 MAY 10 W 14

According to the Air Transport Association of America, the average operating cost of an MD-80 jet airliner is $2,087 per hour. Suppose the operating costs of an MD-80 jet airliner are normally distributed with a standard deviation of $173 per hour.(Round the value of z to 2 decimal places. Round your answers to 2 decimal places.) (a) At what operating cost would only 23% of the operating costs be less?$enter the dollar amount at which only 23% of the operating costs would be less (b) At what operating cost would 65% of the operating costs be more?$enter the dollar amount at which 65% of the operating costs would be more (c) What operating cost would be more than 85% of operating costs?$enter the dollar amount that would be more than 85% of operating costs

A mechanic sells a brand of automobile tire that has a life expectancy that is normally distributed, with a mean life of 36,000 miles and a standard deviation of 2100 miles. He wants to give a guarantee for free replacement of tires that don't wear well. How should he word his guarantee if he is willing to replace approximately 10% of the tires? Click to view page 1 of the table. Click to view page 2 of the table. CHE Tires that wear out by miles will be replaced free of charge. (Round to the nearest mile as needed.)

Suppose that the heights of adult men in the United States are normally distributed with a mean of 70 inches and a standard deviation of 3.5 inches. What proportion of the adult men in the United States are at most 6 feet tall? (Hint: 6 feet 72 inches.) Round your answer to at least four decimal places.
