Random pages were chosen from a variety of children’s books and the number of words on each page was recorded. find the variance of the sample pages. 10 15 8 16 14 12 9 12 14 10 a. 7.3 b. 2.4 c. 2.7 d. 1.5 just give a straight up answer. you!

the answer is 2.7

Step-by-step explanation:

The variance of the given sample is 7.3

Hence the option A. 7.3 is correct

Step-by-step explanation:

The formula of Variance is:

x                                  

10                                           4

15                                           9

8                                           16

16                                          16

14                                           4

12                                           0

9                                             9

12                                            0

14                                            4

10                                            4

Therefore, the variance is:

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
