Question

**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*.

Answer #1

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

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:...

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 survey reported that the mean starting salary for college
graduates after a three-year program was $34,170.Assume that the
distribution of starting salaries follows the normal distribution
with a standard deviation of $3190. What percentage of the
graduates have starting salaries: (Round z-score

A survey reported that the mean starting salary for college
graduates after a three-year program was $34,180.Assume that the
distribution of starting salaries follows the normal distribution

The dean of a college is interested in the proportion of
graduates from his college who have a job offer on graduation day.
He is particularly interested in seeing if there is a
difference in this proportion for accounting and
economics majors. In a random sample of 200 of each type of major
at graduation, he found that 70 accounting majors and 60 economics
majors had job offers. Assume pooled estimate of the population
proportion and a level of significance...

The average student loan debt for 2016 college graduates who
borrowed to get through school was $37,172. Is this still true
today? You get a random sample of 150 recent college graduates and
find that their mean student loan is $36,654 with a standard
deviation of $4,000. Test the claim at the 5% significance level
using PHANTOMS.
