The sample proportion is a point estimate of the population proportion. Therefore we need to convert the given percentage to a decimal fraction to find the best point estimate.
35/100 = 0.35
The best point estimate is 0.35.

Answer:  Option 'b' is correct.

Step-by-step explanation:

Since we have given that

Number of people showed in a recent poll = 1800

Percentage of people believe gas prices will go down = 35%

So, best point estimate of the proportion of all people who believe gas prices will go down is given by

\frac{35}{100}\\\\=0.35

and Number of people who believe gas prices will go down is given by

0.35\times 1800\\\\=630

Hence, Option 'b' is correct.
