Any non-integer answers in this problem should be entered as decimals rounded to the tenth.
Cameron counted the number of stamps on each page in his collection book. The data is shown below.

Use the data to complete the sentences.

The mean of the number of stamps on each page is .
The median of the number of stamps on each page is

The mean of the data set is 22.1 , and the sample proportion of numbers less than the mean is 0.53

Explanation:

.

1) Mean

Formula: mean = sum of values / number of data

sum of values = 25.5 + 26 + 18.2 + 15.3 + 28.5 + 27 + 20.7 + 20.2 + 26.1 + 18.2 + 21.4 + 17.9 + 24.3 + 22.6 + 19.6 = 331.5

number of data = 15

mean = 331.5 / 15 = 22.10

2) proportion of numbers less than the mean

This is easier if you order the data. These are the data in growing order:

15.3

17.9

18.2

18.2

19.6

20.2

20.7

21.4

22.6

24.3

25.5

26

26.1

27

28.5

 The discontinues line shows the split of the data that are less than the mean.

Those are 8 numbers less than 22.1 and the proportion is:

8 / 15 = 0.53

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
