Question

A survey asks students who walk or ride a bike to school whether they live more than one mile from school. The results are shown in the table. Based on the results, which conclusion is best?

Answer 1

Answer: The only correct option is the first one (top left)

Step-by-step explanation:

let's take each conclussion and see if it is true or not.

a) the number of students that live more than a mile away from school is 42

Of those, 32 ride a bike to reach the school.

The proportion is p = (32/42)*100% = 76.19%

We can round it to the whole number, and have P = 76%

then this statement is true.

b) The number of students that ride a bike is 59, the number of students that live less than a mile away and ride bike is 27, the percentage is:

p = (27/59)*100% = 45.7%

this statement is false.

c) Again, 59 students ride a bike, 32 of them live more than a mile away, the percentage here is:

p = (32/59)*100% = 54.23%

this statement is false.

d) We already find that from the students that live more than a mile away, a 76% ride a bike, so this statement is also false.
