4) In your first assignment you analyzed data from a speeding experiment. The purpose of the experiment was to examine the impact of legal penalties and safety consideration on speeding behavior. As part of the experiment, participants were randomly assigned with p=.5 to one of two traffic enforcement conditions. In one they were told that because it was holiday weekend, traffic enforce would be increased and in the other condition they were told that due to a budget crisis, traffic enforcement was curtailed. They were subsequently asked their perception of the risk of being stopped for speeding under these two conditions. The variable labeled "risk pullover" in the table below measures their perceptions. Risk_pullover was measured on a scale for 0% (no chance of being stopped) to 100% (will be stopped for sure).

Clearly, state the null and alternative hypothesis, show your calculations for doing the hypothesis test, and state your conclusion. Conduct the test for a=.03
