Two fuel additives are tested to determine their effect on miles per gallon for passenger cars. Test results for 12 cars follow; each car was tested with both fuel additives. Use a = .05 and the Wilcoxon signed-rank test to see whether there is a significant difference between the median miles per gallon for the additives.

researchers wanted to determine if carpeted rooms contained more baterica than uncapted rooms. to determine the amount of bacterica in a room reseachers pumpled the air from the room over a petri dish at the rate of 1 cubic foot per minute for eight carpeted rooms and eight uncaprted rooms. colonies of baterica were alled to form in 16 petri dishes. the results shown below are the baterica counta per cubic foot mean standard deviation sample size capeted room 11.2 2.6774 8 uncapted room 9.7875 3.21 8 you want ti test using sigificance level of 0.01 whether the mean bactiria count is high for carpeted rooms than for uncapteed rooms. test whether the mean bacteria count is high for carpeted rooms thatn uncarpeted rooms. show all steps using the p value method. what is Ho and H1? what is the test statsic and p value? what conclusion can be made?

Create a Histogram manually or using Excel for the following average gas mileage: 24, 17, 14, 22, 25, 26, 38, 42, 24, 12, 28, 19, 32 21, 35 28, 21, 31, 18, 19. The class intervals are 10-14, 15-19, 20-24, 25-29, 30-34, 35-39, 40-44. Provide your interpretation of the result!
Is the height (in inches) of students in this class a quantitative or qualitative variable?
The weight of a car can influence the mileage that the car can obtain. A random sample of 19 cars was taken and the weight (in pounds) and mileage (in mpg) were recorded and are in the table below. X, weight Y, mileage 3000 31.4 4500 19.5 4000 23.6 4500 17 4000 23.1 3500 28 4000 23.4 3500 31.3 3500 32.6 2250 41.1 4000 23.6 2500 40.9 2750 36.3 3500 28 2750 46.9 3000 32.2 3000 31.4 2250 53.3 3500 31.3 a) The symbol and value of the correlation coefficient are as follows: Round final answer to 4 decimal places. = Interpret this value: There is a strong relation between weight and mileage for cars. b) The symbol and value of the coefficient of determination are as follows: Round final answer to 4 decimal places. = Interpret this value: About % of the explained by the linear model and weight c) Find the standard error of estimate.
