Find the mean, the standard deviation, and the standard error of the mean for this sample.
If you were to calculate the margin of error for the average number of seeds at 90% and 95% confidence, which would be smaller? Briefly explain your reasoning without doing the calculations.
Calculate the 90% and 95% confidence intervals for the mean number of seeds in a one-pound scoop.
Compare the widths of these two intervals. Does this comparison support your answer to part (b)? Explain.
