b. Complete the following concerning the distribution of X. X? ( - For the group of 44 tires selected, find the probability that the average amount of miles used is between 71.8 and 73.5 thousand miles. + 7.02 P(71.8 The average number of miles (in thousands) that a car's tire will function before needing replacement is 72 and the standard deviation is 11 and is normally distributed. Suppose that 44 randomly selected tires are tested. Check off the following that are true. At least one must be true. On > 30 X is normally distributed Complete the following table for the distribution of X and X. Round the standard deviation of X (standard error of the mean) to four decimal places as needed. Sample size Mean Standard deviation X X Distribution Select an answer Select an answer a. Complete the following concerning the distribution of X? X- ? ( If a single (n = 1) randomly selected individual tire is observed, find the probability that this tire lasted between 71.8 and 73.5 thousand miles. 39 P(71.8
