A few years ago, a new drug for pain relief was approved for prescription-only use in the US. Insurance records show that the mean copayment for a month's supply of this drug is $120. A single investigation ofn=50

users generated a sample mean copayment of $107. If we were to collect 1000 samples of sizen=50

from the population of all copayments for a month's supply of the drug, compute the sample means, and plot them on a dotplot, describe the shape you would expect to see in the plot and where it would be centered.
