Answer:
To calculate the standard error of the sample proportion, you can use the formula:
Standard Error (SE) = sqrt [(p * (1 - p)) / n]
Where:
p is the population proportion (0.65 since 65% prefer chocolate, which is 0.65 as a decimal).
n is the sample size (1000 people).
Let's plug in these values and calculate the standard error:
SE = sqrt [(0.65 * (1 - 0.65)) / 1000]
SE = sqrt [(0.65 * 0.35) / 1000]
SE = sqrt [0.2275 / 1000]
SE = sqrt (0.0002275)
IT IS ≈
So, the correct answer is (b) 0.01508.
