Q1. 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. These data are analyzed by an analysis of variance, and the results are reported in the following summary table. Fill in all missing values in the table. (Hint: start with the df column.) With a=.05, detemine whether there are any significant differences among the conditions. If necessary, use the Tukey HSD posttest to determine which groups are significantly different.

Q1. 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. These data are analyzed by an analysis of variance, and the results are reported in
the following summary table. Fill in all missing values in the table. (Hint: start with the
df column.) With a=.05, determine whether there are any significant differences among
the conditions. If necessary, use the Tukey HSD posttest to determine which groups are
significantly different.
