I'D APPRECIATE IT IF AN EXPERT WOULD PLEASE ANSWER THIS QUESTION, SHOWING THE HANDWRITTEN SEQUENCE & STEPS INVOLVED (NOT EXCEL)?

THANK YOU SO MUCH !

6. Continuing with your study of traffic fatalities, you have been charged with figuring out what policy would best curb the death rate. You discover that states have tried a number of solutions, including raising the drinking law to 21, mandating the use of seat belts and helmets, and setting a maximum speed limit of 65 miles per hour. However, vou also wonder whether states that pass one of these measures are also more likely to pass another, and have constructed the following table indicating how many states have passed mandatory seat belt laws and/or have imposed a 65 mile per hour speed cap (Note that the variable 65MPHAllowed takes on the value "yes" if a state does NOT have a speed limit law and the value "no" if the state DOES have a speed limit law. This variable takes on no other values than 0 or 1 .) | Mandatory seatbelt 65 MPH I allowed l law no yes l Total no yes I 34 I 42 Total I 42 I 50 a) [2 points] What percentage of states has passed both seat belt laws and speed limit laws? Show your work b) [2 points] Of the states that have imposed a 65 MPH speed limit, what percentage does not mandate seat belts? Show vour work c) [4 points] Test the claim that states which pass mandatory seat belt laws tend also to impose 65 MPH speed limits. Is there a relationship? Why or why not?

Explanation / Answer

Solution:

(a): %of states that has passed speed limit law and seat belt law both

States which have passed both the laws = 8

Total no. of states = 50

So % of states that has passed speed limit law and seat belt law both = 8/50 = 0.16 or 16%

(b) States which has imposed speed limit law but not mendate seat belt law = 0

Total no. of states = 50

So % of states that has imposed speed limit law but not mendate seat belt law = 0/50 = 0%
