Okay thank you, so if i understood I use Sacramento. by using a table I found z=2.1 with 98.21%. I wanted to know if I was doing the right thing. Because I am still a little confused. Do I need to use this formula z=(x-μ) /σ ? or I need to use the formula with a p?

thank you so much for your help I think I finished question A, B and C. However I did not understand what to do for question D. I have several calculations before t get to the result?

okay. So that should be μ=68000, σ=20000 ? Then I found z=1.6. I did p(z>1.6)=1-0.9452=0.0548 So that means only5.48% that a store manager in Sacramento has a salary in excess of $100,000? If what I did it write i need to do the same for question B, C and D ?

Thank you so much for your answer. I drew my bell curve. Then, I did not really understand what I have to do. Do I need to use p(x>100000) and to calculate z ? I did a bell curve. I was going to use p(x>100000) by calculating z. Is it good if i do that ?

Hello, I need to finish that for tonight and I dont know what to use and what to do. If anyone can help me that would be great.
