Type Small Medium Medium Compact Compact Compact Medium Medium Large Large Medium Compact Large Large Medium Large Compact Sporty Sporty Large Compact Sporty Weight 2700 3265 2935 2670 2790 2895 3640 2880 3350 3325 3465 2640 4285 3545 3480 4025 2655 3110 3320 3855 2485 3280 Use SAS JMP or R to answer the following questions were applicable. (a) Is it reasonable to assume that the five groups may be considered as independent groups? Explain your answer. (2) (b) What graphical technique(s) would you need to decide that the five groups may be considered as coming from normal populations? (2) (c) What are the estimates oks}; Sz; sz; and ? (5)
(d) (i) Compute the “ordinary” average of the five variances computed in (a). (2) (ii) Compute the MSE according to the definition in the study guide. What do you notice?(2)
(f) Plot the five means. (4) (9) Test whether the mean weights for the different types of cars (i.e. the population means of the five groups) differ significantly at the 5% level of significance. Justify your answer by giving attention to the following detail. (1) State the appropriate null and alternative hypothesis for this test. (ii) What test statistic is used to test these hypotheses? (iii) What is the value of the test statistic? (10)
(h) Perform multiple comparisons on all pairs of means using Each Pair, Student’t test and dis- cuss your results. From your results can you conlcude whether that Ismall U medium = Mlarge -(10) Previous question Next question
