Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $40,000 and $54,200. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. (Round your answers up to the nearest whole number.)
What is the planning value for the population standard deviation?
(a)
How large a sample should be taken if the desired margin of error is $600?
(b)
How large a sample should be taken if the desired margin of error is $300?
(c)
How large a sample should be taken if the desired margin of error is $100?
(d)
Would you recommend trying to obtain the $100 margin of error? Explain.

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 =...

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....
