Extracted text: Sugary Caffeine: Part A A small coffee shop manager wants to get a better sense of how much sugar her customers are taking with their coffee. During one shift they took note of how many "sugars" each customer would order with their coffee by keeping track of the number of customers ordering no sugar, 1, 2, 3, or 4 sugars with their coffee. At the end of the shift they had the following table of frequencies (number of customers ordering) for 0, 1, 2, 3, or 4 sugars. Frequency of X=x Relative frequency of x-P(X=x) (# of sugars) X = 0 х, same as P(X=x) 26 ... X = 1 38 X = 2 25 X = 3 16 X = 4 Sums: If the manager wants to use this information to help plan how much sugar to buy each week, what is the expected number of sugars that a typical customer would purchase? Round your answer to 2 decimal places.


Extracted text: Sugary Caffeine: Part B In order to also get a better idea of how varied the day-to-day amount of sugar used could be, the manager also wants to get an idea of how spread out the data is. Calculate the standard deviation for the expected number of sugars calculated previously. Show all of your calculations needed to get the final answer. If you are using Excel, you must include at least one sample calculation for each calculation done, not just the final answers given by Excel (I need to see what you did in each step). Round your answer to 2 decimal places. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). BI U S Paragraph Arial 10pt •..
