- A recruiter at Salisbury University is interested in comparing the percents of high school seniors who plan to go to college in two different regions of the country. The boxplots of the distributions of the percents of seniors who plan to go to college are shown below. Compare the distributions of the percents of seniors who plan to go to college in the two regions. The recruiter combined the data from the two regions to produce a single histogram. Describe the shape of the distribution of the combined data.arrow_forwardFor the following description of data, identify Who and Whatwere investigated and the population of interest. A researcher wondered whether drivers treat bicycle riders differently when they wear helmets. He rigged his bicycle with an ultrasonic sensor that could measure how close each car was that passed him. He then rode on alternating days with and without a helmet. Of the 4000 times that a car passed him, he found that when he wore his helmet, motorists passed 3.07 inches closer to him, on average, than when his head was bare. What is the Who in this study? That is, identify the cases under study.arrow_forwardA sample of blood pressure measurements is taken from a data set and those values (mm Hg) are listed below. The values are matched so that subjects each have systolic and diastolic measurements. Find the mean and median for each of the two samples and then compare the two sets of results. Are the measures of center the best statistics to use with these data? What else might be better?

The committee is analyzing, among other things, data on household incomes in two cities within the county. They have collected data on the income of 80 households in each of the two cities. The histograms below show the distributions of the two sets of incomes (in thousands of dollars). Each histogram shows household income on the horizontal axis and number of households on the vertical axis. The means and standard deviations for the data sets are also given.
