Question

Among the students surveyed at four local high schools, we observed that 42.00% of boys (n=50) and 33.88% of girls (n=62) reported purchasing lunch from their school cafeteria at least 3 times a week. Thus, we can conclude that 37.50% of students in this sample purchase lunch from their school cafeteria at least 3 times a week.

True

False

Answer 1

It is false

we have 42% of boys and 333.88% of girls who purchase lunch from their school cafeteria at least 3 times a week

So, taking the mean or average of boys and girls %, we get

average % = (number of data values)/(total number of data values) = (42+33.88)/2 = 75.88/2 = 37.94%

So, we can say that 37.94% of students in this sample pruchase lunch from their school cafetria at least 3 times a week.

So, it is false because 37.94% is greater than 37.50%.
