(Round to three or more decimal places.)O Maya has two ways to travel from her home in Norco to her office in Los Angeles. One is to go via the 10 Freeway, and the other is to go via 60 Freeway. Inorder to determine which way she should travel on a daily basis, Maya has recorded the travel times for samples of eleven trips via the 10 Freeway and eleventrips via the 60 Freeway. The following table gives the travel times (in minutes) for the twenty-two trips.Travel times in minutes10 Freeway 74, 72, 75, 75, 74, 72, 67, 67, 75, 69, 7160 Freeway 70, 80, 69, 71, 69, 77, 68, 79, 74, 79, 77Send data to calculatorSend data to ExcelAssume that the two populations of travel times are normally distributed and that the population variances are equal.Can we conclude, at the 0.05 level of significance, that u,, the mean travel time via the 10 freeway, is different from µ,, the mean travel time via the 60freeway?Perform a two-tailed test.

Among 2073 passenger cars in a particular region, 222 had only rear license plates. Among 339 commercial trucks, 51 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.10 significance level to test that hypothesis. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. a. Identify the null and alternative hypotheses for this test. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks.
