b. The required percentage is $30.59\%$

c. The required percentage is $9.589\%$

d. The percentage is$37.44\%$

Step-by-step solution

Given Information

It is given that:

Determining percent of the students who responded were Facebook users.

Number of students responding to Facebook users are $148$

Total students are 219

Hence, students responding to Facebook users are$\frac{148}{219}=67.58\%$

Percentage of students were aged 28 or older.

Students which are aged $28$or older are$67$

Hence, percentage is

$\frac{67}{219}=30.59\%$

Percent of the students who responded were older Facebook users

Students responding for older Facebook users are $21$

Percentage$=\frac{21}{219}=9.589\%$

Percent of the Facebook users in the sample were younger students

Students responding for youngers $=82$

Percentage$=\frac{82}{219}=37.44\%$
