Step 3 keep getting that one wrong
myopenmath. assess2/?čid=101459&aid=7240148#/skip/2 The manager of Frenchies IS concerned that patrons are hot consistently receiving the same amount of French fries with each order. The chef claims that the standard deviation for a 14-ounce order of fries is'less than 1 ounces. To test the chef's claim, the manager randomly weighs 66 orders of fries with the following results (in ounces): 15, 14.1, 13.8, 13.1, 14.3, 13.3, 15.4, 14.7, 13.4, 15.1, 14.6, 13.1, 14.3, 13.4, 13.6, 15.3, 13.6, 14.8, 13, 13.9, 14.6, 13.2, 12.6, 13.5, 13.3, 14.4, 15.2, 13.3, 14.4, 14.2, 14.1, 13, 14, 14, 14.4, 14.4, 15, 12.7, 13.6, 14.2, 13, 13.3, 13, 12.9, 14.3, 14.8, 13.8, 14.3, 13.6, 14.3, 14.3, 15.3, 14.6, 12.3, 14, 13.4, 14.2, 13.6, 12.3, 14.2, 14.7, 13.5, 14.9, 14.7, 14.3, 13.3 Perform a hypothesis test using a 3% level of significance to test the chef's claim. Step 1: State the null and alternative hypotheses. Ho:0 2v 1 Ha:o <v 1 (So we will be performing a left-taled v test.) Part 2 of 4 Step 2: Assuming the null hypothesis is true, determine the features of the distribution of test statistics. Because we are testing the population standard deviation, we will use a x distribution with 65 V degrees of freedom. Part 3 of 4 Step 3: Find the p-value of the test statistic. Sample Mean: a 13.9515 Sample Standard Deviation: s = 0.76203 P(x s 0.0027 p-value = 0.0027
