Hi I am needing some help for my daughter with her first year business degree question, I have posted the question below? can anybody help thanks
The weekly salary paid to employees of a small company that supplies part-time laborers averages $700 with a standard deviation of$400.

1) If the weekly salaries are normally distributed, estimate the fraction of employees that make more than $300 per week. 2) 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?

3) If every employee receives a 5% salary increase for the next year, how does the normal model change?

4) If the lowest salary is $300 and the median salary is$500, does a normal model appear appropriate?

Suggests she stop asking you for help and to do her own research. She is at university now and should be doing these things for herself.
