b. The required percentage is $30.59 %$

c. The required percentage is $9.589 %$

d. The percentage is $37.44 %$

Step by step solution

It is given that:

Number of students responding to Facebook users are $148$

Total students are 219

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

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

Hence, percentage is

\frac{67}{219} = 30.59 %

Students responding for older Facebook users are $21$

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

Students responding for youngers $= 82$

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