Question

researchers asked 300 families whether they were homeowners or not and how many cars they had. their responses are summarized in the following table.

	homeowner	not a homeowner
two or more cars	132	93

(a) what percentage of the families have two or more cars?
(b) what percentage of the families are not homeowners?

Explanation:

Step1: Calculate total number of families

The total number of families surveyed is 300.

Step2: Calculate number of families with two or more cars

The number of families with two or more cars is \(132 + 93=225\).

Step3: Calculate percentage of families with two or more cars

The percentage is \(\frac{225}{300}\times100\% = 75\%\).

Step4: Calculate number of non - homeowner families

The number of non - homeowner families is \(93+54 = 147\).

Step5: Calculate percentage of non - homeowner families

The percentage is \(\frac{147}{300}\times100\%=49\%\)

Answer:

(a) 75%
(b) 49%
