# Question: Certain radial tires had useful lives of 35 200 41 000 44 700

Certain radial tires had useful lives of 35,200, 41,000, 44,700, 38,600, and 41,500 miles. Assuming that these data can be looked upon as a random sample from an exponential population, use the estimator obtained in Exercise 10.51 to estimate the parameter θ.
