In intaglio printing, a design or figure is carved beneath the surface of hard metal or stone. Suppose that an experiment is designed to compare differences in mean surface hardness of steel plates used in intaglio printing (measured in indentation numbers), based on two different surface conditions-untreated and treated by lightly polishing with emery paper. In the experiment, 40 steel plates are randomly assigned-20 that are untreated, and 20 that are treated. The results of the experiment are in the “Intaglio” data in Chapter 10_HW_Data.xls. Assuming that the population variances from both conditions are equal, is there evidence of a difference in the mean surface hardness between untreated and treated steel plates? (use α = 0.05) Determine the p-value in (a) and interpret its meaning. In addition to equal variances, what other assumption is necessary in (a)? Repeat Problem (a), assuming that the population variances from untreated and treated steel plates are not…

Suppose we have a balanced one-way ANOVA, with 10 observations in each of 4 groups. The total sum of squares was found to be 2000. The sum of squares due to error (AKA residual) was found to be 900. What is the value of the one-way ANOVA F test statistic? (Give your numeric response to at least 3 decimal places. Give only the numeric response, and not any extra characters or symbols.)
You conduct a one-factor ANOVA with 6 groups and 5 subjecis in each group (a balanced design) and obtain F = 2.48. Use Excel to find the requested values (report accurate Lo 4 decimal places). dfiuiwmn = dfanhin = P=
