With reference to the Example 19, find the probability that such a battery will not last 100 hours.

Data From Example 19

EXAMPLE 19 A large sample test of the mean amount of cheese Refer to Example 8, Chapter 5, where the manufacturer of a pizza like product mea- sures the amount of cheese used per run. Suppose that a consumer agency wishes to establish that the population mean is less than 71 pounds, the target amount estab- lished for this product. There are n = 80 observations and a computer calculation gives x = 68.45 and s = 9.583. What can it conclude if the probability of a Type I error is to be at most 0.01?
