The weekly salary paid to employees of a small company that supplies part-time laborers averages $750 with a standard deviation of $450. (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 median salary is $525, does a normal model appear appropriate? (a) if the weekly salaries are normally distributed, the fraction of employees that make more than $300 per week is approximately nothing. (type an integer or a fraction.)
