Ch 4, worksheet 7

What is in the honeymoon salad?
Lettuce alone with no dressing.

I thought the Chapter 4 reading was pretty straightforward in the beginning. I understood the concepts until I read the whole explanation. I suppose it just became convoluted. I did not understand the purpose of the characteristics of the sample mean especially the sum of squares. I understand the concept, but I do not know what it is used for.
