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 C02 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? E Click the icon to view the data. What are the hypotheses for this test? O A. Ho: H1 # H2 # H3 H1: H1 = H2 = H3 O B. Ho: H1 = H2 = H3 H1: H1 # H2 # H3 O C. Ho: At least one of the means is different from the others. H1: H1 = H2 = H3 O D. Ho: H1 = H2 = H3 H1: At least one of the means is different from the others. Determine the test statistic. F = (Round to two decimal places as needed.) %3D Identify the P-value.

Use the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway bet two entries, use the -score halfway between the corresponding z-scores. If convenient, use technology to find the z-score. P7

5% is a very common significance level for significance tests, but it Is arbitrary a. Give an example where you might want to use a significance level lower than 5%. Explain why you would use the lower level. b. Give an example where you might want to use a significance level higher than 5%. Explain why you would use the higher level

Q3.3 Normal, but why? A meal package for use at the space station is to be prepared by combining three separate components: protein, fruit/vegetable, and grains. Each of the components is to be randomly selected. Summary values for the caloric content for each of the components are given in the table. Component Protein (P) Fruit/vegetable (F) Grain (G) Mean (calories) 120 55 84 Stdv (calories) 6.4 Save Answer 1.0 3.6 Assume that the distributions of caloric content for each of the components are approximately normally distributed. Since the meal package consists of protein, fruit/vegetable, and grains, the total caloric content of a meal package is the random variable T, where T = P + F + G. Briefly explain why it is appropriate to say that T is approximately normally distributed. Q3.4 Probability Less than 275 Calories On your own piece of paper find the approximate probability that a randomly selected meal package will have less than 269 calories?

Night Owls proportion of MSU students who regularly sleep less than 8 hours each night is less than the value reported by the MSU psychologist. She randomly selects 215 students and asks them, "Do you regularly sleep less than 8 hours each night?" She finds that 90 of the 215 students answered "yes" to the question. A MSU psychologist reports that 45% of MSU students regularly sleep less than 8 hours each night. Cindy believes that the actual
The accompanying data set includes volumes (ounces) of a sample of cans of regular Coke. The summary statistics are n = 36, x = 12.199 oz, s = 0.100 oz. Assume that a simple random sample has been selected. Use a 0.01 significance level to test the claim that cans of Coke have a mean volume of 12.00 ounces. Does it appear that consumers are being cheated? Click the icon to view the data set of regular Coke can volumes. Identify the null and alternative hypotheses. Ho: H₁: (Type integers or decimals.
