The number of miles that regular tires last has a Normal distribution with a mean of 50,000 miles and a standard deviation of 8,200 miles. A competitor creates a new brand of tire, SuperWear Tires. The number of miles that SuperWear lasts has a Normal distribution with a mean of 75,000 miles and a standard deviation of 15,500 miles. If a random sample of 16 regular tires is selected and a random sample of 25 SuperWear tires is selected, the probability that the sample mean number of miles of SuperWear is greater than the sample mean number of miles obtained by the regular tires is approximately 1
