Lab 4 reminder: don't confuse the sample size with the number of repeated samples

Open the inspector for "sample of Pennies" (blue balls) to set the sample size n. You are going to try n = 5, 10, 20. The histogram and summary table is created from "measures of sample of pennies". From the summary table you read the s.d. of the sample mean, which is defined as the "standard error".
Open the inspector for "measures from sample of pennies" (green balls) to set the number of repeated samples to 100. Once you set a new sample size n, click on "Collect more measures", and see how the histogram/summary table changes.
