It is suspected that higher priced automobiles are assembled with greater care than lower priced automobiles. To investigate whether there is any basis for this idea, a large luxury model A, a medium size sedan B, and a subcompact hatchback C were compared for defects when they arrived at the dealer's showroom. All cares were manufactured by the same company. The results of the computations are provided in the summary of ANOVA table below.

- a. Given the following information obtained from three normally distributed populations, construct an ANOVA table. (Round intermediate calculations to at least 4 decimal places. Round "SS" to 2 decimal places, "MS" to 4 decimal places, and "P" to 3 decimal places.) SSTR = 186.2; SSE = 2,387.2; c = 3; n = n2 = n3 = 10 ANOVA Source of Variation SS df MS p-value Between Groups 0.363 Within Groups Total b. At the 1% significance level, what is the conclusion to the ANOVA test of mean differences? O Do not reject Ha. we cannot conclude that some means differ. O Reject Ho: we can conclude that some means differ. O Do not reject Ha: we can conclude that some means differ. O Reject Ha, we cannot conclude that some means differ.arrow_forward1. in one-way ANOVA, identify the statistic used as a measure of variation among the sample means. as a measure of variation within the samples. to compare the variation among the sample means to the variation within the samples. 2.

- 18. The governor of New York has banned selling or purchasing "large" soft drinks, where a "large" is defined as being more than 16 oz. Sonic, famous for its Route 44 drinks is interested in estimating the proportion of New Yorkers that favor this ban. From a random survey of 800 New Yorkers, 375 answered no to the question, “Do you favor the governor's ban on 'large' soft drinks?" a. Find a 97.5% confidence interval for the proportion of New Yorkers who favor the ban on "large" soft drinks. b. Interpret the confidence interval. c. Can you conclude with 97.5% confidence that a majority of New Yorkers favor the ban on "large" soft drinks? Why or why not. d. Without doing any other calculations, can you be 99% confident that a majority of New Yorkers favor the ban on “large" soft drinks?arrow_forward1.
