The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.025 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions? A. Determine the test statistic. F= (Round to two decimal places as needed.) B. Identify the P-value. P-value= (Round to two decimal places as needed.)

T he number of awards earned by students at one high school is recorded. Predictors of the number of awards earned include the type of program in which the student was enrolled (e.g., vocational, general or academic) and the score on their final exam in math. Below is a description of the variables and their levels of measurement Variables Student ID - NOMINAL Math Scores - RATIO Total # of awards - DISCRETE Program Type - NOMINAL (categorical with three levels: (1)general, (2)academic, (3)vocational) Total Students= 200 Total Awards = 194 Total math scores = 10529 Program Type sum = 405 Describe the modality (i.e., shape) of this distribution (please be sure to include the appropriate statistics to support your description)

Use the data below to test the claim that the weight loss was greater with the low fat diet compared to the low carbohydrate diet. Use a 10% level of significance. Low Fat Low Carbohydrate x¯1=3.9lbs s1=4.2lb n1=51 x¯1=2.6lb s1=5.9lb n1=79 Identify the tail of the test What is the P-value? Will the null hypothesis be rejected? Is the initial claim supported?
H0: μ ≤ 16.09 vs. HA: μ > 16.09What is the test statistic for sample of size 25, mean 13.97,and standard deviation 1.48?
The test statistic, t, is - 22.67. (Round to two decimal places as needed.) The P-value is 0.000. (Round to three decimal places as needed.) State the conclusion for the test. A. Reject the null hypothesis. There is sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. B. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. C. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. D. Reject the null hypothesis. There is not sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda.

K A company is developing a new high performance wax for cross country ski racing. In order to justify the price marketing wants, the wax needs to be very fast. Specifically, the mean time to finish their standard test course should be less than 55 seconds for a former Olympic champion. To test it, the champion will ski the course 8 times. The champion's times (selected at random) are 54.9, 63.7, 48.1, 53.9, 49.3, 47.4, 53.7, and 44.9 seconds to complete the test course. Should they market the wax? Assume the assumptions and conditions for appropriate hypothesis testing are met for the sample. Use 0.05 as the P-value cutoff level. Choose the correct null and alternative hypotheses below. Ο A. Ho:μ = 55 HAH55 Calculate the test statistic. ... t= OB. Ho:μ>55 HA:μ = 55 OD. Ho:μ<55 HAH=55 (Round to three decimal places as needed.) Calculate the P-value. P-value= (Round to four decimal places as needed.) Choose the correct clusion below. A. No, do not market the wax as there is insufficient…
