Hello Mr Glenn,I have viewed your answer and it was wrong. When I presented it to my instructor, she said the answer was irrelevant to what she was asking, but I asked her to give me an option of making up for it and she gave me another assignment which I did correctly and by myself. Unfortunately the answer you gave me had nothing to do with what she was looking for. She replaced it with another assignment to do. I will contact you again soon because I will be given some homework questions soon and will probably need your help. Thank you.
Expert:  Mr. Glenn replied 4 months ago.

ok, if you have math or stat,I can easily do that.I saw you posted several math/stat questions for the past days (but you requested another expert)

Customer: replied 4 months ago.
I did, I just wasn't sure if you were going to be able to help me out with those.
Expert:  Mr. Glenn replied 4 months ago.

I am a math/stat professor in college for almost 20 yrs. That is really my forte, (those questions you have posted)

Customer: replied 4 months ago.
I understand, that question was a bit tricky and off math topic, but I was able to make up for it. No worries whenever I get a true math question and I need your help I will contact you again. I was tested on this question last week and got it wrong.
