Exam 13: Experimental Design and Analysis of Variance

Exhibit 13-4 In a completely randomized experimental design involving five treatments, thirteen observations were recorded for each of the five treatments. The following information is provided.SSTR = 200 (Sum Square Between Treatments) SST = 800 (Total Sum Square) -Refer to Exhibit 13-4. The number of degrees of freedom corresponding to within treatments is

Individuals were randomly assigned to three different production processes. The hourly units of production for the three processes are shown below. Use Excel with $\alpha$ = 0.05 to determine if there is a significant difference in the mean hourly units of production for the three types of production processes.

Exhibit 13-7 The following is part of an ANOVA table, which was the results of three treatments and a total of 15 observations. -An ANOVA procedure is used for data obtained from four populations. Four samples, each comprised of 30 observations, were taken from the four populations. The numerator and denominator (respectively) degrees of freedom for the critical value of F are

In a completely randomized experimental design, 14 experimental units were used for each of the 5 levels of the factor (i.e., 5 treatments). Fill in the blanks in the following ANOVA table.

A term that means the same as the term "variable" in an ANOVA procedure is
