(26) A company is interested in determining whether the average life of HP and Epson printers is different. A sample of HP and Epson printers result in the following: HP: average life-7 years Standard deviation -2 years n- 10 Epson: average life = 5.5 years Standard deviation-2.5 years n-8 At a-.05, is there a statistically significant difference between the longevity of the two brands of printers?

The weekly salary paid to employees of a small company that supplies part-time laborers averages s800 with a standard deviation of $500. (a) If the weekly salaries are normally distributed, estimate the fraction of employees that make more than $300 per week. (b) If every employee receives a year-end bonus that adds $100 to the paycheck in the final week, how does this change the normal model for that week? (c) If every employee receives a 5% salary increase for the next year, how does the normal model change? (d) If the lowest salary is $300 and the meltian salary is $550, does a normal model appear appropriate?
