Answer:
The point estimate for the proportion of potential car buyers that would consider buying a hybrid vehicle is 0.63.
Explanation:
We are given that in a sample of 600 potential car buyers, 376 indicated that they would consider purchasing a hybrid gas/electric-powered car.
The point estimate for the proportion of potential car buyers that would consider buying a hybrid vehicle is represented by =

where,
Here X = Number of car buyers who indicated that they would consider purchasing a hybrid gas/electric-powered car = 376
n = Total number of sample of car buyers = 600
So, point estimate,
=
= 0.63
Hence, the point estimate for the proportion of potential car buyers that would consider buying a hybrid vehicle is 0.63.
