Question

use a dot - plot to display the data, which represent the systolic blood pressures (in millimeters of mercury) of 24 patients at a doctors office. describe any patterns. 120 135 140 145 130 150 120 170 145 125 115 110 160 180 200 150 200 135 175 120 130 170 165 140. which dot plot below displays the data?

Explanation:

Step1: Count frequency of each value

Count how many times each systolic - blood - pressure value appears in the data set: 120 appears 4 times, 135 appears 3 times, 140 appears 3 times, 145 appears 2 times, 130 appears 2 times, 150 appears 3 times, 170 appears 2 times, 125 appears 1 time, 115 appears 1 time, 110 appears 1 time, 160 appears 1 time, 180 appears 1 time, 200 appears 2 times, 175 appears 1 time, 165 appears 1 time.

Step2: Match with dot - plots

Check each dot - plot to see if the frequencies of the values match the counts from Step 1.

Answer:

(Without seeing the actual visual details of the dot - plots A, B, C, D, it's not possible to give a specific letter answer. But the general process to find the answer is as above. If you describe the dot - plots in more detail, the specific answer can be provided.)
