Answer:

Range = 32

Variance = 87.4

Standard deviation = 9.3

Step-by-step explanation:

Range is the difference between the largest and smallest numbers.

Range = 37 - 5 = 32

Variance is the average of the sum of squared differences between values and their mean.

So mean = sum of values ÷ 10

Mean= 92/10=9.2

Therefore Variance = [(6-9.2)² + (9-9.2)² + ... + (37-9.2)²] ÷ 10

= 87.36

Standard deviation= square root of variance

= √87.36

= 9.3
