Question: Random samples
a. Use a random number table (or a random number generator in a computer or calculator) to select 5 distinct random numbers between 00 and 99. Find the 5 rectangles with these numbers, using 00 to represent rectangle number 100, and mark them on the sheet. This is your random sample of five rectangles.
b. Compute the areas of these five sampled rectangles, and find the average. How does the average of the random sample compare with your guess in step 1a? How does it compare with your average for the subjective sample?
c. The instructor will collect the averages from the random samples of size 5 and construct a dot plot. How does this plot compare with the plots of the guessed values and the averages from the subjective samples in terms of center? In terms of spread?
