In the Sampling and What is average videos they spoke about the average person has  1.89 feet.  They took nine people, each having two legs except for one that lost his leg  to cancer. It equates to 17 feet. Eight of the people had two legs, and one person had  only one leg. 8 x 2= 16+1=17. 17ft divided by nine gave an average of 1.89 feet per  person. It is equal to the mean number of feet in the population (the population you want to apply the results ). This was not a good random sample because it would not pertain  to the average population. A good random sample would be ten people playing bingo, and 100 balls were placed in the machine. Each ball that comes out of the device is random and unbiased. Everyone  would have an equal opportunity to win. Because the balls are picked random and  unbiased, the statistical conclusion would be valid from this analysis. The same for the

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
