This question explores the effect of the sample size on the sampling distribution of the mean. a)
Open Excel. Select Data Analysis, then select "Random Number Generation" from the available
options. Use the following values when prompted to enter them: Click OK. Rename the new
worksheet to Q4_a There will be 80 rows and 7 columns filled with numbers in a new Sheet on
Excel. Consider each row as a random sample drawn uniformly from the numbers 1 to 10. In this
case, you have 80 samples of size 7 . In the first empty cell of the following empty column, enter a
formula for the mean of the sample in the first row, then drag this formula down to the last row. In
this case, you should enter the formula =AVERAGE(A1:G1) into cell H1. Dragging the formula
down from cell H1 to H80 to find the remaining sample means..
