The data table shows the ages in years of 10 men with systolic blood pressure. The Age,x: 18, 26, 39, 46, 48, 64, 68, 31, 58, 22. and systolic blood pressure, y: 111, 123, 145, 130, 201, 183, 198, 131, 177, 119. The sample correlation coefficient r is 0.881. Remove the data entry for the man who is 48 years old and has a systolic blood pressure of 201 millimeters of mercury from the data set and find the new correlation coefficient.
Suppose that, at the end of last semester, Marie gave her introductory statistics class a final exam. After grading these exams, she created a histogram illustrating the distribution of exam scores for the 70 students in the class. Each of the bars in this histogram includes only the left endpoint of the interval, except for the bar representing scores between 90 and 100 points, which also includes the right endpoint. What percentage of students scored between 60 and 80 points on the exam? Round your answer to the nearest tenth of a percent. Number of students who scored at least 80 points = students Percentage of students who scored between 60 and 80 points = %
The following are the exam scores for a new literature class: 34, 41, 90, 80, 18, 20, 25, 70, 25, 20, 50, 40, 36. The class follows a typical grading scare where 65% is the lowest passing gradeand 100% is the highest. Create a box plot. Be sure to identify all thenecessary terms. What can we infer from looking at the box plot?

A County Board of Supervisors has appointed an urban planning committee to evaluate proposed community development projects. 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.

Nicole has a popular blog about cooking and nutrition and regularly posts articles and videos. She has collected data about the length of time that viewers spent watching two of her recent videos. For each video, she recorded the amount of time (in minutes) that each of 102 viewers spent watching it. The histograms below show the distributions of the two data sets. Each histogram shows time (in minutes) on the horizontal axis and the number of viewers on the vertical axis. The means and standard deviations for the data sets are also given.
