Using it's concepts, the mean and the standard deviation of the data-set are given as follows:
B. mean: 17; standard deviation: 7.53.
<h3>What are the mean and the standard deviation of a data-set?</h3>- The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.
- The standard deviation of a data-set is given by the <u>square root of the sum of the differences squared between each observation and the mean, divided by the number of values</u>.
The mean for this problem is:
M = (22 + 21 + 20 + 4 + 19 + 6 + 24 + 11 + 26)/9 = 17
The standard deviation is:
Hence option B is correct.
