If it’s assumed the area represented by these yellow pages is at least 500,000, do you think that the number of bakeries (12) sampled in our case study was large enough to be valuable in planning the new business?

Look in the “big” yellow pages for your area (try to choose a book that represents a population of about 500,000 or so). Count the number of bakery entries. Respond to the following: (USE SAN ANTONIO FOR THE AREA)
1. If it’s assumed the area represented by these yellow pages is at least 500,000, do you think that the number of bakeries (12) sampled in our case study was large enough to be valuable in planning the new business?
2. Was there any indication in the case study that our sample was random?
3. The standard deviation is one of the most important concepts in the area of statistics. In your own words, define standard deviation. Give an example of how you have used the concept of standard deviation in your life.
4. Suppose you are a grocery store owner (perhaps next-door to the bakery). You order apples from two different vendors and pay the same per pound to each supplier. You evaluate the two shipments and find that a sample of 7 apples from supplier A weighs (in ounces) [12, 13,15, 10, 9, 11, 12]. The sample of 7 apples from supplier B weighs (in ounces) [11, 8, 12, 16, 7, 9, 17]. Without doing any calculations, tell us which supplier you’d rather use and why.
