an ice cream company surveyed 1000 random individuals to see if they prefer chocolate or vanilla ice cream. of those surveyed, 550 preferred chocolate. the ice cream company simulated the survey and found the margin of error to be 40. what does the margin of error mean in relation to this survey? move numbers to the blanks to complete the sentence. the population mean for individuals preferring chocolate is estimated as being a value within the interval of ____ to ____ because ____ % of the sample means from the simulation trials fell within this interval. 40 55 95 510 550 530 570 590

Answer

Explanation:

Step1: Calculate lower - bound

The sample proportion of those who prefer chocolate is 550 out of 1000. The margin of error is 40. The lower - bound of the confidence interval is the sample value minus the margin of error. So, $550 - 40=510$.

Step2: Calculate upper - bound

The upper - bound of the confidence interval is the sample value plus the margin of error. So, $550 + 40 = 590$.

Step3: Recall confidence level concept

In a common statistical simulation, 95% of the sample means from the 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.
