“SmartB” owns a phone battery assembly line which provide phone battery to a mobile company. It is known that 4% of the batteries produced by “SmartB” are defective. A random sample of 28 phone batteries is selected from the assembly line and will be sent for inspection. d). The production cost of a phone battery is $100 and the selling price to the mobile company is $500. When the phone battery is found defective within a year, it could be sent back for repairment, which costs “SmartB” $70. Suppose all defective phone battery would be reported by the customer within a year and would be sent back for repairment. Present the probability distribution function of the profit gained by “SmartB” from a phone battery. (Remark: Profit = revenue – cost) e). Calculate the expectation, variance, and standard deviation of the profit gained by “SmartB” from a phone battery.
