Hi, I'm Josie and I am a moderator for this topic. I sent your requested professional a message to follow up with you here, when he is back online.
If I can help further, please let me know. Thank you for your continued patience.
Martin can you type out the null hypothesis and alt hypothesis separately so I can add them into my work. I have to put them in two separate blocks and I can't seem to type them in separately. Thanks new assignments coming your way.
I checked it over, and everything looks fine. The hypotheses are correct, as are the numbers. Do you have any more information about what your instructor is unhappy with?
Martin I hate to bother you but this is what my instructor sent. I only received partial credit to pass class I have to get full credit for assignment.
this is what he sent.
