Question

in anatomy, a student learned that the average resting heart rate is between 60 and 100 beats per minute. the student decided to record the heart rate of people over five minutes while waiting in line at the pharmacy. the dot plot shows the results. which statement below best describes the shape of the distribution? the data is roughly symmetrical distributed, with most values clustered from 68 to 80 beats per minute. the values at 62 and 89 are possible outliers. the data fits within the average of 60 to 100 beats per minute. the data is not symmetrically distributed, with most values clustered from 68 to 80 beats per minute. the values at 62 and 89 are possible outliers. the data fits within the average of 60 to 100 beats per minute. the data is skewed right, with fewer values on the right end of the graph. the values at 62 and 89 are possible outliers. the data fits within the average of 60 to 100 beats per minute. the data is skewed left, with fewer values on the left end of the graph. the values at 62 and 89 are possible outliers. the data fits within the average of 60 to 100 beats per minute.

Explanation:

Symmetrical data has a similar shape on both sides of the center. Here, most values cluster from 68 - 80. Values 62 and 89 are far - off points (outliers). The data's overall shape is roughly the same on both sides of the center range, indicating rough symmetry.

Answer:

The data is roughly symmetrical distributed, with most values clustered from 68 to 80 beats per minute. The values at 62 and 89 are possible outliers. The data fits within the average of 60 to 100 beats per minute.
