7. In a random sample of 250 toner cartridges, the mean number of pages a toner cartridge will print is 4302 and the standard deviation is 340. The data is known to follow a bell curve. What percent of the time should a cartridge print between 3962 and 4982 pages? What percent of the time should a cartridge print more than 4642 pages? Suppose a toner cartridge printed 5000 pages. What conclusion, if any would you make? Would a toner cartridge that only printed 4000 pages be 'statistically unusual'? Why or why not
