Explanation:

We are given a table that shows the data of two samples regarding the favorite outdoor activity of 100 students as:

Sample Canoeing Bike Racing Reading Total

1 40 35 25 100

2 45 40 15 100

1)

It is more than the number of students who prefer bike racing and reading combined.

From sample 1 the combined number of students who love bike racing and reading is: 35+25=60

From sample 2 the combined number of students who love bike racing and reading is: 40+15=55

Hence, in both the samples the number of people who love bike racing and reading combined are more than those who prefer canoeing.

Hence, option (1) is incorrect.

2)

It is less than the number of students who prefer bike racing and reading combined.

As done in option (1) we get option (2) is correct.

3)

It is equal to the number of students who prefer reading.

This option is incorrect.

Since,

Canoeing Reading

Sample 2: 45 15

This option is also incorrect.

Since,
