- Mike Mochado is the head barrista at John's Java & Jerk, a local cafe serving coffee, cold beverages, and food items with a Carribbean flair. Mike's big concern at the moment is deciding how many pounds of coffee beans he'll need for the week. The guy from corporate told Mike to assume that coffee bean usage is normally distributed. On the basis of the cafe's first 20 weeks of operation, Mike has determined that his average weekly coffee bean usage is 153.75 pounds, with a standard deviation of 55.35 pounds. How many pounds of coffee beans should Mike have on hand to be 95.9 % sure that he'll have enough beans? F−1(0.959)=F−1(0.959)=Using the Hamwi method, calculate the IBW for a 48 year old male who weighs 78 Kg, is 185 cm tall and is extremely active, and has a large body frame sizeThe weights in pounds of a breed of yearling cattle follows the Normal model N(1089,57).

- A company that manufactures rivets believes the shear strength (in pounds) is modeled by N(750,30). Use the 68–95–99.7 Rule to complete parts a) through c) below. a) Draw and label the Normal model. b) Would it be safe to use these rivets in a situation requiring a shear strength of 720 pounds? Explain. Choose the correct answer below. A. No, because about 32% of all of this company's rivets have a shear strength of less than 720 pounds. B. Yes, because very nearly all of this company's rivets have a shear strength of more than 720 pounds. C. No, because about 16% of all of this company's rivets have a shear strength of less than 720 pounds. D. Yes, because only about 2.5% of all of this company's rivets have a shear strength of less than 720 pounds. c) About what percent of these rivets can be expected to fall below 810 pounds?Given below is the revenue that Tesco recorded ov location over the last five vears:Do the following on paper, scan or photograph your work, and submit it.
