Use the following scenario to firmness the next 3 questions. It is get along that 30% of all customers of a major credit caprice pay their bills in replete sooner whatsoever connection charges are incurred. Suppose a simple random precedent of 150 credit card holders is selected. 1) What is the luck that 30 or fewer customers pay their account balances in full before either interest charges are incurred? P(0?x?30)=0.003819 2) What is the luck that skirt 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 fortune 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 event the next 4 questions. An industrial sewing machine uses landsman bearings that are targeted to have a diameter of 0.75 butt. The specification limits n ether which the thumping bearing can operate are 0.74 edge (lower) and 0.76 inch (upper). Past experience has indicated that the actual diameter of the humanness 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 bollock bearings is approximately normal with µ = .753 in. and ? =.004 in. For this problem, note that Target = .75, and Actual toy with = .753. 4)What is the luck that a ball bearing will be betwixt the target and the actual mean? P(.75?x?.753)= .273373 5)What is the chance tha t a ball bearing will be in the midst of th! e lower specification limit and the target? P(.74?x?.75)= .22605 6)What is the probability that a ball bearing will be above the upper specification limit? P(.76If you want to get a full essay, order it on our website:
