2) Some people argue that an average speed is not a great indicator of a speeding problem. Instead, they think the proportion of cars that speed is far more important. If more than 30% of vehicles are driving faster than 5 mph over the speed limit (driving faster than 50 mph), this could indicate a speeding problem. Conduct an appropriate hypothesis test if more than 30% of vehicles on North Main Street are going faster than 50 mph at the 0.025 significance level. You can decide whether to make the decision using critical values and a rejection region or using a p-value. Show all steps in the test. Hint: to obtain p, you'll need to look back at the data file to find the sample proportion of vehicles who were found to be traveling faster than 50 mph (not equal to 50 mph). It is easiest to count this manually.
