Use the following scenario to firmness the next 3 questions. It is go to sleep that 30% of all customers of a major credit inclination pay their bills in effective in the beginning whatsoever affaire charges are incurred. Suppose a simple random quantity of 150 credit card holders is selected. 1) What is the luck that 30 or fewer customers pay their account balances in full before some(prenominal) interest charges are incurred? P(0?x?30)=0.003819 2) What is the luck that environ by 40 and 50 customers pay their accounts balances in full before any interest charges are incurred? P(40?x?50)=0.672974 3) What is the hazard that more(prenominal) than 60 customers pay their accounts balances in full before any interest charges are incurred? P(61?x?150)=0.00349 Use the following scenario to termination the next 4 questions. An industrial sewing machine uses screwball bearings that are targeted to have a diameter of 0.75 butt. The specification limits under which the thumping bearing can operate are 0.74 adjoin (lower) and 0.76 inch (upper). Past experience has indicated that the actual diameter of the solid ground bearings is approximately normally distributed with a slopped of 0.753 inch and a standard deviation of 0.004 inch. So we have that the diameter of the ball bearings is approximately normal with µ = .753 in. and ? =.004 in. For this problem, note that Target = .75, and Actual besotted = .753. 4)What is the chance that a ball bearing will be betwixt the target and the actual mean? P(.75?x?.753)= .273373 5)What is the probability that a ball bearing will be mingled with the lower specification limit and the target? P(.74?x?.75)= .22605 6)What is the probability that a ball bearing will be in a higher place the upper specification limit? P(.76If you want to get a full essay, order it on our website: OrderC ustomPaper.com
