Gnagey's Gknives claim they will last at least year 10 years without needing to be sharpened. Consumer Reports randomly samples 42 knives, and calculates that they need to be sharpened on average in 9.25 years. Based on other knife sharpening studies, suppose that the population standard deviation is known to be 1.7 years. Consumer Reports wants to conduct a hypothesis test at 0.01 level of signicance. What is the best interpretation of the results of the hypothesis test? 0 Because the p-value is greater than alpha, we reject the null hypothesis, and conclude that there is statistical evidence that Gnagey's Gknives claim is incorrect 0 Because the p-value is less than or equal to alpha, we fail to reject the null hypothesis, and conclude that there is statistical evidence that Gnagey's Gknives claim is correct 0 Because the p-value is less than or equal to alpha, we reject the null hypothesis, and conclude that there is statistical evidence that Gnagey's Gknives claim is incorrect 0 Because the p-value is greater than or equal to alpha, we reject the null hypothesis, and conclude that there is statistical evidence that Gnagey's Gknives claim is correct 0 Because the p-value is greater than alpha, we fail to reject the null hypothesis, and conclude that there is statistical evidence that Gnagey's Gknives claim is correct 0 Because the p-value is greater than alpha, we fail to reject the null hypothesis, and conclude that there is statistical evidence that Gnagey's Gknives claim is incorrect 0 Because the p-value is less than or equal to alpha, we reject the null hypothesis, and conclude that there is statistical evidence that Gnagey's Gknives claim is correct 0 Because the p-value is less than or equal to alpha, we fail to reject the null hypothesis, and conclude that there is statistical evidence that Gnagey's Gknives claim is incorrectStep by Step Solution
