Cola Weights For the four samples described in Exercise 1, the sample of regular Coke hasa mean weight of 0.81682 lb, the sample of Diet Coke has a mean weight of 0.78479 lb, thesample of regular Pepsi has a mean weight of 0.82410 lb. and the sample of Diet Pepsi has amean weight of 0.78386 lb. If we use analysis of variance and reach a conclusion to reject equal-ity of the four sample means, can we then conclude that any of the specific samples have meansthat are significantly different from the others?3. Cola Weights For the analysis of variance test described in Exercise 1, is that test left-tailed,right-tailed, or two-tailed?4. Cola Weights Identify the value of the test statistic in the display included with Exercise 1.In general, do larger test statistics result in larger P-values, smaller P-values, or P-values thatare unrelated to the value of the test statistic?5. Cola Weights The displayed results from Exercise I are from one-way analysis of variance.What is it about this test that characterizes it as one-way analysis of variance instead of two-wayanalysis of variance?6. One-Way ANOVA In gencral, what is onc-way analysis of variance used for?7. One vs. Two What is the fundamental difference between one-way analysis of variance andtwo-way analysis of variance?

A researcher takes sample temperatures in Fahrenheit of 17 days from New York City and 18 days from Phoenix. Test the claim that the mean temperature in New York City is different from the mean temperature in Phoenix. Use a significance level of α=0.05.

A certain producer of chocolate has some problems with the variability of five suppliers of cocoa. Since the cocoa quality is critical to the final chocolate product, the company has decided to perform a DOE to compare these suppliers. According to experiences with customers, the capacity of detection of any variation is 3.5 units. Estimate the sample size needed to get at least a power of 85%, given that the historical variance of the process is 2.5 units.
