On May 16, 2017, Verdun Hayes of Somerset, Great Britain set a new Guinness World Record: the oldest ever skydiver. The World War II veteran, who fought on thebeaches of Normandy in 1944, set a new record when he skydived at age 101.Suppose the ages of all skydivers follow a normal distribution with mean 52.8 years and standard deviation 10.3 years. Based on this distribution, how old must a skydiver be to fallin the top 1.32% of the distribution?75.03375.66972.24229.931

It is given that Mean, μ = 52.8 Standard deviation, σ = 10.3

A mechanic sells a brand of automobile tire that has a life expectancy that is normally distributed, with a mean life of 29,000 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. Tires that wear out by miles will be replaced free of charge. (Round to the nearest mile as needed.)

Over the first five years of owning her car, Gina drove about 12,700 miles the first year, 15,478 miles the second year, 12,675 the third year, 11,850 the fourth year, and 13,075 the fifth year. a. Find the mean, median, and mode of this data. b. Explain which measure of central tendency will best predict how many miles Gina will drive in the sixth year. a. mean= 12,700; median= 13,156; no mode; the mean is the best choice because it is representative of the entire data set. b. mean= 13,156; median= 12,700; mode= 3,628; the median is the best choice because it is not skewed by the high outlier. c. mean= 13,156; median= 12,700; no mode; the mean is the best choice because it is representative of the entire data set. d. mean= 13,156; median= 12,700; no mode; the median is the best choice because it is not skewed by the high outlier.
