A recent poll of 1800 people showed that 35% believe gas prices will go down. Find the best point estimate of the proportion of
2 answers:
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
and Number of people who believe gas prices will go down is given by
Hence, Option 'b' is correct.

If you're asking for extrema, like the previous posting
well
like the previous posting, since this rational is identical, just that the denominator is negative, the denominator yields no critical points
and the numerator, yields no critical points either, so the only check you can do is for the endpoints, of 0 and 4
f(0) = 0 <---- only maximum, and thus absolute maximum
f(4) ≈ - 0.19 <---- only minimum, and thus absolute minimum
