Kira 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. In order to determine which way she should travel on a daily basis, Kira has recorded the travel times for samples of eight trips via the 10 Freeway and eight trips via the 60 Freeway. The following table gives the travel times (in minutes) for the sixteen trips. Travel times in minutes 10 Freeway 71, 75, 69, 65, 65, 66, 72, 68 60 Freeway 76, 76, 66, 79, 74, 70, 72, 77 Send data to calculator Send data to Excel Assume that the two populations of travel times are normally distributed and that the population variances are equal. Can we conclude, at the 0.10 level of significance, that u,, the mean travel time via the 10 freeway, is different from u,, the mean travel time via the 60 freeway? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)

Blake and April are both taking AP Calculus, but they have different teachers who have two different grading systems. Blake is in Mr. Frey’s class and April is in Coach Smith’s class. Blake is mad because she thinks that with her averages, she would have a higher average in Coach Smith’s class. Given her averages below, what would be her overall average for each class? Round to the nearest whole number.

In 2010, the number of people living in each state House district was about 167, 637, since the population was determined by the U.S. census at 25, 145, 561 million. Suppose the population is determined to be at or around 30 million, in 2020. About how many people will be living in each House district after the state redraws district boundaries. O about 200,000 about 20,000 about 967,741 about 96, 774

Determine how various attributes impact the purchase of a car. There are four attributes, each with three levels. • Brand: Ford = 0, Chrysler = 1, GM =2 • MPG: 15 MPG = 0, 20 MPG = 1, 25 MPG = 2 Horsepower (HP): 100 HP = 0, 150 HP = 1, 200 HP = 2 • Price: $18,000 = 0, $21,000 = 1, $24,000 = 2 The nine product profiles ranked below were evaluated by a consumer: (note - the table should be reproduced using the dummy variables) |(F, C, GM) |(15, 20, 25) |(100,150, 200) (18000, 21000, 24000) Trial Brand MPG Power Price Rank 4 2 1 1 2 7 2 1. 3 4 1. 1. 1. 2 1 9. 7 2. 2 8 8. 2 1 5 9 1 1 Q27.

Rita 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. In order to determine which way she should travel on a daily basis, Rita has recorded the travel times for samples of twelve trips via the 10 Freeway and twelve trips via the 60 Freeway. The following table gives the travel times (in minutes) for the twenty-four trips.   Travel times in minutes 10 Freeway 66, 70, 73, 71, 72, 71, 65, 74, 69, 71, 75, 71 60 Freeway 77, 72, 71, 68, 74, 80, 70, 78, 76, 71, 68, 67 Assume that the two populations of travel times are normally distributed and that the population variances are equal. Can we conclude, at the 0.01 level of significance, that the mean travel time via the 10 freeway, μ1, is different from μ2, the mean travel time via the 60 freeway? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and…

One common system for computing a grade point average​ (GPA) assigns 4 points to an​ A, 3 points to a​ B, 2 points to a​ C, 1 point to a​ D, and 0 points to an F. What is the GPA of a student who gets an A in a 33​-credit ​course, a B in each of threethree 22​-credit ​courses, a C in a 33​-credit ​course, and a D in a 22​-credit ​course?
