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

Answer 2

Answer:

Option: A is the correct answer.

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

Step-by-step 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. )
