Consider an experiment to determine the effects of alcohol and marijuana on driving. Five randomly selected subjects were given alcohol to produce legal drunkenness and then are given a simulated driving test (10 a top score; 0 a bottom score). Five different randomly selected subjects are given marijuana and the same driving test. Finally, a control group of five subjects is tested for driving while sober.
Mean St. Deviation
Alcohol 2.4 1.3
Drugs 3.6 1.8
Control 6.8 1.3
State the null and alternative hypotheses. What is the obtained F and the critical F at the .05 alpha level? Do you accept or reject the null hypothesis? If necessary, calculate the Tukey’s HSD and determine which groups are significantly different from each other.

To illustrate the effects of driving under the influence of
alcohol, a police officer brought a DUI simulator to a local high
school. Student reaction time in an emergency was measured with
unimpaired vision and also while wearing a pair of special goggles
to simulate the effects of alcohol on vision. For a random sample
of nine teenagers, the time (in seconds) required to bring the
vehicle to a stop from a speed of 60 miles per hour was recorded....

Randomly selected statistics students participated in an
experiment to test their ability to determine when 60 seconds has
passed. Forty-six students yield a sample mean=57.43 seconds with a
sample standard deviation=9.04 seconds. Use α=0.05 as a
significance level to test the claim that the population mean
equals to 60 seconds.

1. Randomly selected statistics students participated in an
experiment to test their ability to determine when 1 min has
passed. Forty students yielded a sample mean of 58.3
sec. Assuming that s = 9.5 sec, use a 0.05 level of
significance to test the claim that the population mean is equal to
60 sec. Be sure and include the appropriate interval
(for alpha = .05, it is a 95% confidence level) in your conclusion.
Conduct a hypothesis test.

Randomly selected students participated in an experiment to test
their ability to determine when one minute (or sixty seconds) has
passed. Forty students yielded a sample mean of 57.5 seconds.
Assuming that sigmaequals9.2 seconds, construct and interpret a
95% confidence interval estimate of the population mean of all
students. hat is the 95% confidence interval for the population
mean mu? Based on the result, is it likely that the students'
estimates have a mean that is reasonably close to sixty...
