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.

Suppose X - N(H, 36 ) and P( X > 6 ) = 0.13. Determine the value of p. (Give your answer to 4 decimal places.)
