The average number of miles (in thousands) that a car's tire will function before needing replacement is 64and the standard deviation is 12. Suppose that 15 randomly selected tires are tested. Round all answers to4 decimal places where possible and assume a normal distribution.a. What is the distribution of X? X - N( 64b. What is the distribution of x? ~ N( 64O 64c. If a randomly selected individual tire is tested, find the probability that the number of miles (inthousands) before it will need replacement is between 64.2 and 66.8.12OBd. For the 15 tires tested, find the probability that the average miles (in thousands) before need ofreplacement is between 64.2 and 66.8.

From the provided information, Mean (µ) = 64 Standard deviation (σ) = 12 Sample size (n) = 15

The chart to the right shows that a professor's grading distribution is bell shaped, or normally shaped. The mean of the distribution is 74 and the standard deviation is 9. Using a Continuous Variable Normal Bell Distribution Model, calculate the minimum test score needed to score in the top 5% of the class. Complete your work in the worksheet by listing the formula inputs, labels for the formula inputs and make your calculations with formulas.
