The Edison Electronic Institute has published figures on the annual number of kilowatt-hours expended by various home appliances. It is claimed that a vacuum cleaner expends less than 46 kilowatts-hour per year. They want to test the hypothesis Ho : M = 46 against Ha: M < 46 In order to test their hypothesis, a random sample of 12 households were taken and included in the study. After computations, the p-value was found to be 0.08. Based on a 0.05 significance level, what would they decide? They should reject the null hypothesis, there is sufficient evidence to show the mean is equal to 46. O They should reject the null hypothesis, there is sufficient evidence to show the mean is less than 46. They should fail to reject the null hypothesis, there is insufficient evidence to show the mean is equal to 46. They should fail to reject the null hypothesis, there is insufficient evidence to show the mean is less than 46
