Chapter 9.4, Problem 9.52LM

A randomized block design was used to compare the mean responses for three treatments. Four blocks of three nonogeneous experimental units were selected, and each treatment was randomly assigned to one experimental unit within each block. The data are shown below, followed by an SPSS ANOVA printout for this experiment.

b. Do the data provide sufficient evidence to indicate that the treatment means differ ? Use α = .05.

c. Do the data provide sufficient evidence to indicate that blocking was effective in reducing the experimental error? Use α = .05.

d. Use the printout to rank the treatment means at α = .05.

e. What assumptions are necessary to ensure the validity of the inferences made in parts b, c, and d?

A test was conducted of two overnight mail delivery services. Two samples of identical deliveries were set up so that both delivery services were notified of the need for a delivery at the same time. The hours required to make each delivery follow. Do the data shown suggest a difference in the delivery times for the two services? Use a .05 level of significance for the test. Use Table 1 of Appendix B. Click on the datafile logo to reference the data.

Consider an experiment to determine the effects of alcohol and marijuana on driving. Five randomly selected subjects are given alcohol to produce legal drunkenness and then are given a simulated driving test (scored from a top score of 10 to a bottom score of 0). Five different randomly selected subjects are given marijuana and then the same driving test. Finally, a control group of five subjects is tested for driving while sober. The driving test scores and the One-Way ANOVA table for these data are shown below. Test the hypothesis that there is a difference among the means of the three groups at 1% significance level.
