Use the following scenario to firmness the next 3 questions. It is slam that 30% of all customers of a major credit liking pay their bills in skillful ahead whatsoever nexus charges are incurred. Suppose a simple random specimen of 150 credit card holders is selected. 1) What is the luck that 30 or fewer customers pay their account balances in full before whatsoever interest charges are incurred? P(0?x?30)=0.003819 2) What is the luck that encircled 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 resolution the next 4 questions. An industrial sewing machine uses landman bearings that are targeted to have a diameter of 0.75 butt. The specification limits un der which the thumping bearing can operate are 0.74 move on (lower) and 0.76 inch (upper). Past experience has indicated that the actual diameter of the human beings 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 roll bearings is approximately normal with µ = .753 in. and ? =.004 in. For this problem, note that Target = .75, and Actual hold still for = .753. 4)What is the fortune that a ball bearing will be betwixt the target and the actual mean? P(.75?x?.753)= .273373 5)What is the luck that a ball bearing will be betwixt th! e 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:
