Answer

Explanation:

Step1: Calculate lower - bound

The number of individuals who preferred chocolate in the sample is 550. The margin of error is 40. The lower - bound of the interval is calculated by subtracting the margin of error from the sample value. So, $550 - 40=510$.

Step2: Calculate upper - bound

The upper - bound of the interval is calculated by adding the margin of error to the sample value. So, $550 + 40 = 590$.

Step3: Recall confidence level concept

In a typical survey with a margin of error, about 95% of the sample means from simulation trials fall within the margin - of - error interval.

Answer:

The population mean for individuals preferring chocolate is estimated as being a value within the interval of 510 to 590 because 95% of the sample means from the simulation trials fell within this interval.
