Question

researchers asked 200 families whether or not they were homeowners and how many cars they had. their responses are summarized in the following table.

	no car or one car	two or more cars
not a homeowner	34	66

(a) what percentage of the families have two or more cars?
(b) what percentage of the families are homeowners?
(a) \\(\square\\%\\)
(b) \\(\square\\%\\)

Explanation:

Part (a)

Step1: Find total families with two or more cars

Families with two or more cars: homeowners (82) + not homeowners (66) = \( 82 + 66 = 148 \)

Step2: Calculate percentage

Total families = 200. Percentage = \( \frac{148}{200} \times 100 = 74\% \)

Step1: Find total homeowners

Homeowners: no car/one car (18) + two or more cars (82) = \( 18 + 82 = 100 \)

Step2: Calculate percentage

Percentage = \( \frac{100}{200} \times 100 = 50\% \)

Answer:

74
