Question

7. Suppose that the starting annual salary in April 2013 for new college graduates who found full time employment is normally distributed with a mean of $48,181 and a standard deviation of $3,708. Find the starting annual salary x0 such that 20% of new college graduates who found full time employment in April 2013 earned less than x0

Answer #1

Starting Salary Problem
In 2013, the mean starting salary for college graduates who major
in Social Work was $45,000. An analyst for a job searching company
claims that the mean starting salary has since decreased. In a
random sample of 38 job posting for social workers, the mean
starting salary was $43,200 with a standard deviation of $9,340.
Test the claim using a significance level of 0.10.
Determine the p-value.
Round your answer to 4 decimal places.

According to a National Association of Colleges and Employers,
the average starting salary for new college graduates in health
sciences is $51,541. The average starting salary for new college
graduates in business is $53,901.† Assume that starting salaries
are normally distributed and that the standard deviation for
starting salaries for new college graduates in health sciences is
$13,000. Assume that the standard deviation for starting salaries
for new college graduates in business is $17,000

An experiment is conducted to compare the starting salaries of
male and female college graduates who find jobs. Pairs are formed
by choosing a male and a female with the same major and similar
grade point averages. Suppose a random sample of 10 pairs is formed
in this manner and the starting annual salary of each person is
recorded. The differences within the pairs are obtained by
subtracting the female salary from the male salary. The following
results are obtained:...

While the average starting salary for graduates with an MBA
degree varies depending on the university attended and field of
emphasis, one source shows a 2015 median annual starting base
salary of $100,000 (source: Claire Zillman, “Congrats, MBA grads!
You’re getting a $45,000 raise,” http://fortune.com, May 19, 2015).
Assuming that starting salaries are normally distributed and the
standard deviation is $20,000, what is the probability that a
random sample of 100 MBA graduates will have a mean starting salary
of...

2. A random sample of 12 recent college graduates reported an
average starting salary of $54,000 with a standard deviation of
$6,000.
To construct a 95% confidence interval for the mean starting
salary of college graduates, what will be the margin of error?
Round to whole dollars.

A sample of 100 college graduates is obtained and the mean
salary is found to be $ 43704 with a standard
deviation of $9879. Find the margin error E associated with a 95%
