Answer:

0.249 is the required proportion.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 822

Number of people who preferred foreign cars over domestic, x = 205

We have to find the proportion of new car buyers who prefer foreign cars.

Formula:

[tex]\hat{p} = \dfrac{x}{n}[/tex]

Putting values, we get,

[tex]\hat{p} = \dfrac{205}{822}\\\\\hat{p} = 0.249[/tex]

Thus, 0.249 is the proportion of the new car buyers who preferred foreign over domestic cars..
