Discussion/ Conclusion ● accuracy/ precision: 1. For accuracy, the 95% confidence interval for this set of data yielded an uncertainty of ± 0.091181 g in the true mean of the pre 1980 pennies. The measurements have a high precision for the data are pretty clustered about the mean. The low standard deviation, 0.0367021621 g, indicates high precision. 2. For accuracy, the 95% confidence interval for this set of data yielded an uncertainty of ± 0.019293 g in the true mean of the post 1982 pennies. The measurements have a high precision because the set has a low standard deviation. 3. For accuracy, the 95% confidence interval for this set of data yielded an uncertainty of ± 0.25182 g in the true mean of the pre 1980 pennies. The measurements have a fairly high precision because the set has a pretty low standard deviation (not as low as those in problems 1 and 2 though). 4. For accuracy, the 95% confidence interval for this set of data yielded an uncertainty of ± 0.0016755 g in the true mean of the post 1982 pennies.
