Rаmp metering is а trаffic engineering idea that requires cars entering a freeway tо stоp fоr a certain period of time before joining the traffic flow. To test whether ramp metering is effective in reducing travel times, engineers conducted an experiment in which a section of freeway had ramp meters installed on the on-ramps. The response variable for the study was speed of the vehicles. A random sample of 15 cars on the highway for a Monday at 6 p.m. with the ramp meters on and a second random sample of 15 cars on a different Monday at 6 p.m. with the meters off resulted in the following summary statistics of vehicle speeds Group Mean Std. dev. n Ramp_Meters_On 41.07 9.64 15 Ramp_Meters_Off 34.8 9.55 15 Is there evidence that the ramp meters are effective in producing higher average speeds on the freeway? Let µ1 = mean for ramp meter ON and µ2 = mean for ramp meter OFF State the null and alternative hypothesis for this test.
