10 7 6 12 11 9 8 13 11 11 12 6 8 7 15 9 12 6 10 10

Compute the Sample mean (x), Sample variance (s² ), and the Sample standard deviation (s).

(round to two decimal places)

Count the number of measurements in the intervals

x ±s, x ±2s, x ±3s.

Express each count as a percentage of the total number of measurements.
