The table below shows data from a survey about the amount of time, in hours, high school students spent reading and the amount of time spent watching videos each week (without reading):

reading video
3 1
3 2
4 3
5 4
6 6
7 7
10 8
12 8
14 9
30 15

which response best describes outliers in these data sets?
a, reading has a suspected outlier in the 30-hour value.
b. reading has a suspected outlier in the 30-hour value, and video has a possible outlier in the 15-hour value.
c. neither data set has suspected outliers.
d. the range of data is too small to identify outliers.

The correct option is: A,B

Step-by-step explanation:

" An outlier is a odd value which on removing from the data leads to the less mean as calculated mean on including that value ".

There are total 10 data points.

3    3    4    5    6     7    10    12    14    30

The mean of this data is given by:

Also the mean after omitting the odd value i.e. 30 we get:

Hence, there is a change in its mean;

Hence the outlier for reading is 30.

1     2     3    4    6    7      8    8     9    15

The possible maximum value here is 15 so we will check whether it is an outlier or not.

The mean of this data is given by:

Also the mean after omitting the odd value i.e. 15 we get:

Hence, there is a change in its mean hence 15 is an outlier.

Hence option A and B are true.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
