Question

Respond clearly and thoroughly, yet concisely, to each of the following questions. Be sure to justify your response, when appropriate.

Assume a researcher is given the following: Three different sections of the same Interstate highway, with roughly equal traffic volumes, have been patrolled by the State Police at different levels of intensity for the past six months. The posted speed limit is 55 and the speeds of a random sample of motorists have been registered for each of the three sections.

LIghtly Patrolled	Moderately Patrolled	Heavily Patrolled

The researcher is interested in whether there exists any statistically significant difference in the speeds. What test of significance should the researcher use and why (i.e. be sure to justify your response). Let’s assume that the researcher conducted the appropriate test of significance and obtained a value of 2.99. What does that value reveal? (That is, offer a thorough interpretation of the test statistic result.)
