For a random sample of 12 business graduates from a technical
college, the starting salaries accepted for employment on
graduation (in thousands of dollars) were the following:
26.2 29.3 31.3 28.7
27.4 25.1 26.0 27.2
27.5 29.8
32.6 34.6
For an independent random sample of 10 graduates from a state
university, the corresponding figures were as follows:
25.3 28.2 29.2
27.1 26.8 26.5 30.7
31.3 26.3 24.9
Analyze the data using the Mann-Whitney test, and comment on the
results.
To get you started, assume that the null hypothesis is that the
median starting salaries are the same for both types of
schools.
Specify the following:
the H0 and H1,
the sum of ranks for the technical college (R1),
the values for n1, n2, U, μ_U, σ_U^2,
the z-score, the p-value, whether you reject or fail to reject
H0, and what is your conclusion?

Annual starting salaries for college graduates with degrees in
business administration are generally expected to be between
$30,000 and $45,000. Assume that a 95% confidence interval estimate
of the population mean annual starting salary is desired. Given the
information in the Microsoft Excel Online file below, construct a
spreadsheet to determine how large a sample should be taken for
each desired margin of error.
For a margin of error of ± $400 , the required sample size is
n =...
