I: 'u The rav.r data om a study are frequently summarized after collection with the consequence that data in terms of means and variances may be all that is available to an analyst. Assume that there is interest in comparing different types of paints in terms of drying times: which three types to be compared. Three, four and five walls in a building are painted with Type I, ]I andl DI paint1 respectively. The average drying times in hours and the variances of the drying times are given below. Paint e Avera e st! 1 45.2 2.3 2 E .4 2.? 3 9.6 4.2 Give the statistical model with assumptions. Give the ANDVA table to compare the mean drying times of three different pain types. Discuss the results. Construct 95% simultaneous C] for the mean differences using the Tukey's method. Discuss the |[31's. Is there any violation on the equal variance assumption? Ifthen, give a proper transformation
