Question
A manufacturer of home products is designing a new wall mount for large flat-panel televisions. Since some flat-panel
televisions weigh up to 100 pounds, the manufacturer wants to make sure that the mean weight of failure for the wall
mounts is greater than 180 pounds. Dayton is a researcher for the manufacturer who is conducting the test. He randomly
selects 35 wall mounts and tests them by using a machine that pulls down on the mounts until each one fails. The results
are shown in the data set provided. Based on the research completed during the development phase, Dayton assumes th
the population standard deviation is 6.9 pounds.
Use Excel to test whether the mean failure weight is greater than 180 pounds. Calculate the test statistic, z, rounding to t
decimal places, and the p-value, rounding to three decimal places.
