(b) find the range of the given data
​

Answer 1

Answer:

(a) 46.29

(b) 46

Step-by-step explanation:

(a)

to get mean:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

So;

37+38+39+40+48+82+40

  = 324 % 7

  = 46.29

(b)

to get range:

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.

So;

82-37

  = 46
