Fourteen different second-year medical students at a hospital measured the blood pressure of the same person. The systolic (mm Hg) are listed below. Use the given data to construct a boxplot and identify the 5-number summary 124 139 136 137 120 125 144 130 130 131 128 140 142 150

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.

Is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis.
