Answer 1

Option: A is the correct answer.

It is more than the number of students who prefer movies and picnics combined.

Explanation:

We are given a table that represents the data collected from two samples as:

Sample Swimming Movies Picnics Total

1 60 30 10 100

2 80 15 5 100

Hence, the observation that can be made regarding the number of students in the club who prefer swimming is:

It is more than the number of students who prefer movies and picnics combined.

( Since, from sample 1--

Combined students who prefer movies and picnics are: 30+10=40

Hence, the number of students who prefer swimming (i.e. 60) is more than the combined number of students who prefer movies and picnic.

Sample-2

Combined students who prefer movies and picnics are:15+5=20

Hence, the number of students who prefer swimming (i.e. 80) is more than the combined number of students who prefer movies and picnic. )

Answer 2

Of the choices offered, the only one that makes any sense is ...

1. It is more than the number of students who prefer movies and picnics combined.
