Question
### Constructing a 95% Confidence Interval for Protein Content To estimate the mean amount of protein in the new protein bar "Energize Original," we assume the protein content in the bars is normally distributed. You sampled 18 bars and determined the mean protein content (\( \bar{x} \)) to be 18.2 grams, with a sample standard deviation (s) of 0.87 grams. **Task:** a. Find the margin of error, \( E \). This exercise involves calculating the confidence interval to provide an estimated range that is likely to include the population mean. The margin of error is a critical component in determining this range and reflects the precision of our sample mean as an estimate of the population mean.
