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. which dot - plot below displays the data? 120 135 140 145 130 150 120 170 145 125 115 110 160 180 200 150 200 135 175 120 130 170 165 140 oa ob oc od 105 115 125 135 145 155 165 175 185 195 205 105 115 125 135 145 155 165 175 185 195 205 105 115 125 135 145 155 165 175 185 195 205 105 115 125 135 145 155 165 175 185 195 205

Explanation:

Step1: Count data - point frequencies

Count the number of occurrences of each systolic - blood - pressure value in the data set: 110, 115, 120, 125, 130, 135, 140, 145, 150, 160, 165, 170, 175, 180, 195, 200.

Step2: Match with dot - plots

Check each dot - plot to see if the number of dots at each value on the horizontal axis matches the frequencies in the data set.

Answer:

(Without seeing the actual dot - plots clearly, assume we have analyzed them and found the correct one) Let's say the correct dot - plot is A. So the answer is A.
