Question

Quizplus · Accepted Answer

The mean of the numbers is calculated by summing them up (4 + 1 + 8 + 14 + 7 + 12 + 16 + 17 + 10 = 89) and dividing by the number of numbers (9), which gives 89/9 = 9.89. The variance is calculated by finding the average of the squared differences from the mean, which is approximately 29.4. The standard deviation is the square root of the variance, which is approximately 5.4.
