Question

find the mean and range. 20 14 29 39 33 25 19 35 a. mean = 25.35; range = 26 b. mean = 28.45; range = 25 c. mean = 26.75; range = 28 d. mean = 26.75; range = 25

Answer 1

the answer is d.mean=26.75 range=25

Answer 2

Option D mean = 26.75 and range = 25 is correct.

Explanation:

To find the mean we use this formula

sum of all quantities / number of quantities.

=
`((20 + 14 + 29 + 39 + 33 + 25 + 19 + 35))/(8)`

Mean = 26.75

Now we find Range. Formula of Range = Maximum - Minimum

39 - 14 = 25

Range = 25

Option D mean = 26.75 and range = 25
