The twoway table represents data from a survey asking schoolchildren whether they are attending a summer camp taking swimming lessons or both Which is the joint class=

Respuesta :

Answer: Last option is correct.

Step-by-step explanation:

Since we have given that

Number of frequency for school children who plan to attend camp and have swimming lessons = 42

And total number of school children surveyed for this purpose = 96

So, Joint relative frequency for school children who plan to attend camp and have swimming lessons is given by

[tex]=\frac{\text{Number of students who takes swimming lessons and attend camp}}{\text{ Total number of students}}\\\\=\frac{42}{96}\times 100\\\\=43.75\%\\\\=44\%\ approximately[/tex]

hence, Last option is correct.

Joint relative frequency for school children who plan to attend camp and have swimming lessons is 44%.

What is the relative frequency?

The relative frequency is the ratio of the subgroup frequency to the total frequency.

The given information follows;

Number of frequency for school children who plan to attend camp and have swimming lessons = 42

The total number of school children surveyed for this purpose = 96

So, Joint relative frequency for school children who plan to attend camp and have swimming lessons is given by

= (total number of students who take swimming lessons and attend / total number of students) × 100

= (42 / 96 )x 100

= 43.75%

= 44%
