Question

A group of 200 high school students were asked about their use of email and text messages. The resultsare shown in the two-way frequency table. Complete the table.

Answer 1

hello

to solve this question, we'll take it part by part to make things easier

we have a total of 200 students

a total of 96 response was gotten for email

71 students requested or accepted the use of email

to get the number of those that responded with no, we would subtract 71 from 96

`\begin{gathered} no=96-71 \\ no=25 \end{gathered}`

now we can work for the number of students that responded to sms

40 students declined or said no to sms

we have a total of (200 - 96) students left to respond to sms

the total number of students that responded to sms is 200 - 96

`\text{total}=200-96=104`

we have 40 students that already rejected the offer of sms, we can subtract 104 from 40 to get the number of students that request for sms

`\text{yes}=104-40=64`

now we can find the grand total for each section

total number of yes = 71 + 64 = 135

total number of no = 25 + 40 = 65

total number of students = 96 + 104 = 200
