Here are the current salaries for Sally's team.
Salary ($) >>Number of Players
300,000 >> 2
500,000 >> 3
Determine the z-score of Sally's current salary of $300,000.
What will the new z-score be if Sally's agent does get her a million-dollar contract?
I need help with the second part. What will the new z-score be if Sally's agent does get her a million-dollar contract?
So I calculated everything you need to know regarding the z-score (and they are correct):
z= (x-u)/ SD
population mean = 1,000,000
so, now I am not sure what x value should go in the z-score formula. I tried 1,000,000, meaning that the z-score would be 0. But, the back of the book says otherwise. Can someone explain to me what value should be x and why? Thanks for your help.
and btw, part a) is -0.87 which I have.. just stuck on part b)
