Open excel
In one column enter 8 heights for 10 year old boys
(inches) and in the second column enter 8 weights
for 10 year old boys
(pounds). Ten
year old boys height ranges from 42 inches to 62
inches while the weight ranges from 60 to 90 pounds. You
can make these up as long as they are reasonable if you do not have
access to any data. We want to see if there is a correlation.
