Problem 1E

In an experiment to measure the lifetimes of parts manufactured from a certain aluminum alloy, 73 parts were loaded cyclically until failure. The mean number of kilocycles to failure was 783, and the standard deviation was 120. Let µ represent the mean number of kilocycles to failure for parts of this type. A test is made of H0: µ ≤ 750 versus H1:µ > 750.

a. Find theP-value.

b. Either the mean number of kilocycles to failure is greater than 750, or the sample is in the most extreme _________% of its distribution.

The answer to “In an experiment to measure the lifetimes of parts manufactured from a certain aluminum alloy, 73 parts were loaded cyclically until failure. The mean number of kilocycles to failure was 783, and the standard deviation was 120. Let µ represent the mean number of kilocycles to failure for parts of this type. A test is made of H0: µ ? 750 versus H1:µ > 750.a. Find theP-value.________________b. Either the mean number of kilocycles to failure is greater than 750, or the sample is in the most extreme _________% of its distribution.” is broken down into a number of easy to follow steps, and 91 words.
