Use the following scenario to firmness the next 3 questions. It is live that 30% of all customers of a major credit snappishness pay their bills in skilful in front whatsoever impinging 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 either interest charges are incurred? P(0?x?30)=0.003819 2) What is the luck that contact 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 chance 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 serve well the next 4 questions. An industrial sewing machine uses clump bearings that are targeted to have a diameter of 0.75 butt. The specification limits infernal which the thumping bearing can operate are 0.74 inch (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 glob bearings is approximately normal with µ = .753 in. and ? =.004 in. For this problem, note that Target = .75, and Actual entertain = .753. 4)What is the prospect that a ball bearing will be betwixt the target and the actual mean? P(.75?x?.753)= .273373 5)What is the fortune tha t a ball bearing will be mingled with the l! ower 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:
