Federal law under Title 49 of the United States Code, Chapter 301, Motor Vehicle Safety Standard took effect on January 1, 1968 and required all vehicles (except buses) to be fitted with seat belts in all designated seating positions. While most states have laws requiring seat belt use today, some people still do not “buckle up.” Let’s assume that 90 % of drivers do “buckle up.” If drivers are randomly stopped to check seat belt usage, answer the following questions and show your work. If they stop 30 cars during the first hour, find the mean and standard deviation of the number of drivers not expected to be wearing seatbelts? If they stop 120 cars during this safety check, what is the probability they find at least 12 drivers not wearing seatbelts?
The table below lists the annual salaries (in dollars) for a sample of 12 high school math teachers in Lousiana and 10 high school math teachers in Florida. Test the claim that high school math teachers in Louisiana get paid more than those in Florida using α=0.10. Louisiana 42300 45500 42100 39600 41500 43700 42500 43200 38400 36800 40100 42500 Florida 38600 35200 33700 41400 40600 39400 37500 36800 42100 36900 Let population 1 be Louisiana high school math teachers and population 2 be Florida high school math teachers. Round the test statistic to two decimal places, and round the p-value to four decimal places. The test statistic is . The p-value is . Should the null hypothesis be rejected?
Students who are home-schooled often attend their local schools to participate in various types of activities such as sports or musical ensembles. According to the government, 82% of home-schoolers receive their education entirely at home, while 12% attend school up to 9 hours per week and 6% spend from 9 to 25 hours per week at school. A survey of 85 students who are home-schooled revealed the following information about where they receive their education. Entirely at home Up to 9 hours 9 to 25 hours 50 25 10 At α=0.05, is there suffificient evidence to conclude that the proportions differ from those stated by the government?
