An editorial in the New York Times on Sunday June 4, 2011 dicussed the redesigned fuel economy stickers to be required on new cars starting in 2013. Consider a new idsize fuord fusion s model. At $4-a-gallon gas, annual fuel costs would be about $2,200 for 15,000 miles driven... And thats for a car with a rated mileage of 34.9m.p.g. actual highway mileage, as with all vehicles, is lower, in this case about 27m.p.g. Industry clearly needs to do better. Did the times use the rated or the actual mileage in its computation?
Burkina Faso, a landlocked country in West Africa, has the lowest adult literacy rate in the world (25.3%). Over the past 15 years, the government has focused heavily on improving access to education across the country. Between 2008 and 2015, the primary school completion rate rose from 40% to 60%, and the high school completion rate doubled over the same period from 15% to 30%. Despite these encouraging statistics, children in rural areas, especially girls, continue to have limited access to quality education. You put together a survey to collect information on the following variables and you are ready to analyze: Gender Age at last birthday Distance from school Level of education (Primary, Secondary, Post-Secondary) Discuss what measure of central tendency is the most appropriate for each variable making sure to explain why.

Jillian Michaels and Bob Harper are all- time famous American trainers. Michaels thinks that her clients lose more weight on average than the clients of Harper. Harper naturally disagrees with Michaels. In order to settle the dispute, the two trainers agree to each work with 15 different clients for six months. The table below summarizes the weight loss (Ibs) of each group: J. В. Michaels Harper Mean 25 21 SD 5.1 2.5 Size 15 15 1. Assume normality in the population distribution, construct a 90% confidence interval for the population difference of the mean weight loss using the critical value of 1.76 (Note: all values are given, no R codes needed) 2. What does it mean to be at "90% confident"? Would the 95% confidence interval be wider or narrower? Would the margin of error be wider or narrower? (Note: no calculation is needed) 3. According to the confidence interval you found in part (a), what can be concluded about Michaels' claim? (Note: you do NOT need to do the 5-step significance…
