Question: Find the margin of error for a 95% confidence interval. Round your answer to the nearest tenths.

Answer: 1.96(19/√16) = 9.31

Question: Find a 95% confidence interval for the mean µ cholesterol content for all experimental eggs. Assume that the population is normally distributed.

Answer:

1.96 – 9.31 = 7.35

1.96 + 9.31 = 11.27

Standard error of the mean = Standard deviation/√(n-1)

95% confidence interval = mean ± 1.96 SE. Why are you not using mean = 186?
