Assume a researcher compared the performance of two independent groups of participants on an ordinal variable using the Mann-Whitney U test. The first group had 8 participants and the second group had 11 participants.
a. Using a p level of 0.05 and a two-tailed test, what is the critical value?
b. Assume the researcher calculated U1 = 22 and U2 = 17. Make a decision regarding the null hypothesis and explain that decision.
c. Assume the researcher calculated U1 = 24 and U2 = 30. Make a decision regarding the null hypothesis and explain that decision.
d. Assume the researcher calculated U1 = 13 and U2 = 9. Make a decision regarding the null hypothesis and explain that decision.

As a business owner faced with an important decision that could potentially be very lucrative.
Make a scatter plot. Do you expect a positive, negative, or zero correlation? Why? Find the correlation coefficient and the equation of the line of best fit and write them down
Let U1 and U2 be independent random variables. Suppose that U1 is χ2 with ν1 degrees of freedom while U = U1 + U2 is chi-square with ν degrees of freedom, where ν > ν1. Then prove that U2 is chi-square random variable with ν - ν1 degrees of freedom.
use the value of linear correlation coefficient r to find the coefficient of determination and the percentage of the
