Using Mann-Whitney U Test!

Pretend you are a string professor at a local university. You have two teaching assistants (TAs) that teach private lessons to students who did not make your studio. The TAs have been arguing back and forth about who is doing a better job preparing students to play in the local community orchestra. After several "discussions", you decide to settle the matter by comparing the chair positions of their former students now playing in the community orchestra. Since the former students are violinists, violists, cellists, and bassists, their chair placement is by section and there may be more than one student per rank. Your assignment is to: 1. Calculate the ranks and insert the answers in the table. 2. Calculate the values for the following and insert answers in the space after each. Note: list two decimal places without rounding when appropriate. n1=n2= TA1 of ranks = TA2 of ranks = TA1U= TA2 U= zscore= p-value = 3. List whether to accept or reject the H0
