The percentage of students with cell phone is 64.92%

Explanation:

Given

Sample Size = 1,220

Number of student with cell phones = 792

Required

Percentage of students with cell phone

To calculate the percentage of students with cell phone, we take a ratio of the number of students with cell phone to the sample size.

Mathematically, this is represented as

`Percentage = (Students-with-cell-phone)/(Sample Size)`

By Substitution,

`Percentage = (792)/(1220)`

`Percentage = 0.64918032786`

`Percentage = 64.918032786`%

`Percentage = 64.92`% Approximated to nearest hundredth

Hence, the percentage of students with cell phone is 64.92%
