Use the Data Below: A) A potential car buyer is undecided on whether to buy a 2012 car with a front-wheel-drive (F) or with a rear-wheel-drive (R).

Each car in a sample of seven cars was tested for nitrogen-oxide emissions (in grams per mile), and the following results were obtained. 0.070.120.160.170.160.070.17 a. Assuming that this sample is representative of cars in use, construct a 95% confidence interval estimate of the mean amount of nitrogen-oxide emissions for all cars. b.One agency requires that nitrogen-oxide emissions be less than 0.181 gram/ mile. Someone claims that nitrogen-oxide emissions have a mean equal to 0.181 gram/mile. Does the confidence interval suggest that this claim is not valid?

A researcher hypothesizes that the average number of sports colleges offer for males is greater than the average number of sports colleges offer for females. Perform an independent samples t chart at a = 0.025 to see whether the number of sports offered for males is greater than females. State the hypotheses and conclusion. Also, conduct a 90% confidence interval. Males Females 9 11 6 8 13 13 8 7 15 5 14 12 12
In a recent study, researchers were interested in the distractions caused by cell phones. In a random sample of 738 cell phone users, approximately 23 percent of the sampled users admitted to walking into somethingwhile talking on their cell phones. 1. Calculate the standard error of the sample proportion of the sampled users who admitted to walking into something while talking on their cell phones. 2. Construct and interpret a 95 percent confidence interval for the population proportion of cell phone users who will admit to walking into something while talking on their cell phones.
