Question

The drinking age in New Jersey is 21. Suppose that New Jersey lowered the drinking age to 18. Use the results in column (4) to predict the change in number of traffic fatalities in the next year.
The predicted (increase/ or/ decrease) in the number of traffic fatalities in the next year is:

Construct a 90% confidence interval for your answer.
The 90% confidence interval for the (increase /or/ decrease) in number of traffic fatalities in the next year is:
