Question
Use the data to compute the probability that a motorcyclist wears a DOT-compliant helmet.
Transcribed Image Text:Use the data to compute the probability that a motorcyclist wears a DOT-compliant helmet.
The National Occupant Protection Use Survey (NOPUS) was conducted to provide probability- based data on motorcycle helmet use in the United States. The survey was conducted by sending observers to randomly selected roadway sites where they collected data on motorcycle helmet use, including the number of motorcyclists wearing a Department of Transportation (DOT)-compliant helmet (National Highway Traffic Safety Administration website, January 7, 2010). Sample data consistent with the most recent NOPUS are shown below. Answer questions 8 -10. Type of Helmet DOT- Region Compliant Noncompliant Northeast 96 62 Midwest 86 43 South 92 49 West 76 16 Total 350 170 (Hint: The above table is a cross-tabulation, but the right margin is missing. You will need to calculate the total number of motorcyclists for each region as well as the total number of motorcyclists of all four regions.)

Expert Solution
Step 1

It is given that

Number of motorcyclist wears a DOT-compliant helmet = 350

Total motorcyclist = 350 + 170 = 520
