It is of interest to determine if the average drying time of a certain brand of latex paint is not 4.5 hours. To do this. 15 cans of the branded latex paint were selected. Normality test of drying time of the branded latex paint ShapiroWill: normality test daLa: dryingLime W 7 0.96961, p-valuc , 0.1396 Which of the following is(are) TRUE at 5% level of significance? I. If the p- value of the appropriate test is 0.0130. the conclusion is "there is sufficient evidence to say that the average drying time of a certain brand of latex paint is NOT 4.5 hours. ll. Suppose that the 95% confidence interval for the true mean drying time of a certain brand of latex paint is [3.25.432]. The NULL HYPOTHESIS WILL BE REJECTED since the hypothesized value of the mean of 4.5 is not within the constructed interval. * O c, Bothland H O D. Neither I nor l| Which of the following is(are) TRUE at 5% level of significance? l. The assumption on the normality of drying time of the branded latex paint is SATISFIED. II. To determine if the average drying time of a certain brand of latex paint is not 4.5 hours, a NONPARAM ETRIC TEST is more appropriate to use than a parametric test. * O c. Bothland H O D. Neither I nor II Which of the following is the most appropriate test to use to determine if the average drying time of a certain brand of latex paint is not 4.5 hours? * O A. Approximate Z-test on one population proportion O B. t-test on one population mean 0 C. Wilcoxon signed-rank test 0 D. Chi-square test on variance
