Perform a hypothesis test for the following problem using An analyst claims that the mean price of a meal for a family of 4 in a resort restaurant is at most $100. A random sample of 33 meal prices for families of 4 has a mean of $110 and a standard deviation of $19. At $\alpha = 0.01$, is there enough evidence to reject the analyst's claim? ORIGINAL CLAIM ALTERNATIVE CLAIM STEP 1 $H_o:$ $H_a:$ STEP 2 Significance level: Type of Test: Critical Value(s): STEP 3 Test Statistic: P-Value: STEP 4 "Fail to Reject $H_o$" "Reject $H_o$" STEP 5 "There is enough evidence to reject the claim that ..." "There is not enough evidence to reject the claim that ..." "There is enough evidence to support the claim that ..." "There is not enough evidence to support the claim that ..." At $\alpha = 0.01$, can you reject the analyst's claim?

We want to check if Steel becomes stronger when Zinc and Copper are added to it during the manufacturing process. The average increase in steel strength is shown below. (The number of replicates =2). No Zinc Moderate Zinc No Copper 8,8.2 10,10.2 Medium Copper High Copper 9,9.2 11,11.2 10,10.2 12.1, 11.9 (a) Draw two interaction plots, one with the levels of Copper on the X axis, and one with the levels of Zinc on the X axis. Is there a lot of interaction between the amounts of Zinc and Copper? [HINT: check if the lines are almost parallel, or not even close to being parallel). Use the average value in each cell when drawing your diagram. For example the average value of strength when Zinc = \"Moderate\" and Copper=\"High\" is 12.0. (b) Run 2-way Anova using XL or R, and attach a screenshot of the results. Is there an interaction effect between Zinc and Copper? [HINT: what is the null hypothesis? Recall that the null hypothesis can be rejected if the corresponding p-value is less than 5%]. (c) Do either Copper or Zinc have an impact on the strength of the steel produced?
