Perform an appropriate hypothesis test for a population mean using the p-value approach.

Last year, the mean running time for a certain type of flashlight battery was 8.5 hours. This year, the manufacturer has introduced a change in the production method which he hopes will increase the mean running time. A random sample of 4 0 of the new light bulbs was obtained and the mean running time was found to be 8.7 hours. Do the data provide sufficient evidence to conclude that the mean running time, ȝ, of the new light bulbs is larger than last year's mean of 8.5 hours? Perform the appropriate hypothesis test using a significance level of 5%. Assume that ı = 0.5 hours.

A statistician would like to construct a hypothesis test of the mean using the P-value approach. Rank the steps that the statistician can follow to carry out this hypothesis test at a level of significance of α. Note that there may be more than one correct answer. Step Rank Collect sample data Define the null and alternative hypotheses Draw a conclusion Calculate the P-value Define the distribution of the test statistic Calculate the test statistic
