A consumer electronics firm has developed a new type of remote control button that is designed to operate longer before becoming intermittent. A random sample of 35 of the new buttons is selected and each is tested in continuous operation until becoming intermittent. The resulting lifetimes are found to have a sample mean of x = 1,241.2 hours and a sample standard deviation of s= 110.8. Assuming normality of the population, the p-value for testing Ho versus Ha can be calculated to be .0174. (a) Determine whether Ho would be rejected at each of a = 10, a = .05, a = .01, and a = .001. Since p-value = .0174, we reject HO for a = but not at a =
