A
15
B
23
C
22
D

Explanation: 

Detailed explanation-1: -To calculate the range, you need to find the largest observed value of a variable (the maximum) and subtract the smallest observed value (the minimum).

Detailed explanation-2: -The range in statistics for a given data set is the difference between the highest and lowest values. For example, if the given data set is 2, 5, 8, 10, 3, then the range will be 10 – 2 = 8.

Detailed explanation-3: -The t-score formula is: t=¯¯¯x−S√n t = x ¯ − S n, where ¯¯¯x is the sample mean, is the population mean, S is the standard deviation of the sample, and n is the sample size.

Detailed explanation-4: -The Range is the difference between the lowest and highest values. Example: In 4, 6, 9, 3, 7 the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple!
