Question

I'll give brainiest to whoever answers both of these correctly

The two-way table shows the results of a survey where students were asked if they were currently in elementary or middle school and if they owned a smartphone.





1)Of the people surveyed, what is the relative frequency of those who own a smartphone? (round to the nearest percent)

2) Of the elementary school students, what is the relative frequency of those who own a smartphone? (round to the nearest percent)

Answer 1

Answer:

1) 45%

2) 24%

Step-by-step explanation:

1) Total number of people surveyed = 26 + 84 + 72 + 34 = 216

    number of people who own a smartphone = 26 + 72 = 98

           ∴ relative frequency = $\frac{98}{216}$   ˣ   100 = 45%

2) Total number of elementary school students = 26 + 84 = 110

               ∴ relative frequency = $\frac{26}{110}$   ˣ   100 = 24%

Hope this helps!
