A report states that the mean yearly salary offer for students graduating with a degree in accounting is $48,757. Suppose that a random sample of 50 accounting graduates at a large university who received job offers resulted in a mean offer of $49,880 and a standard deviation of $3500. Do the sample data provide strong support for the claim that the mean salary offer for accounting graduates of this university is higher than the national average of $48,757? Test the relevant hypotheses using α = 0.05. (Use a statistical computer package to calculate the P-value. Round your test statistic to two decimal places and your P-value to three decimal places.)

Suppose the average yearly salary of an individual whose final
degree is a master's is $3333 thousand less than twice that of an
individual whose final degree is a bachelor's. Combined, two people
with each of these educational attainments earn $117 thousand. Find
the average yearly salary of an individual with each of these final
degrees.

A administrator wants to know what is the average starting
salary, μ, for students graduating from her college. She is able to
obtain data for 100 randomly selected students. For these 100
students, the average is $70,000, and the SD is $10,000. What is a
99% confidence interval for μ?

Question 1
The mean starting salary of job with certain degree is unknown.
Based on a sample of starting salary of 25 employees, the mean
salary turns out to be $45,750/year. Assume that the population of
all starting salaries follows a normal distribution with standard
deviation $9125.
To find a 95% confidence interval estimate of mean staring
salary, what interval estimate will you use?
Group of answer choices
T-interval
Z-interval

The College Board wanted to test whether students graduating
from private colleges and students graduating from public
universities had different amounts of student loan debt. A sample
of students from 146 private colleges across the country yielded an
average loan debt of $29,972 with a standard deviation of $3,200. A
sample of students from 225 public universities yielded an average
loan debt of $28,762 with a standard deviation of $5,600. Conduct
the test at the α=0.02α=0.02 level of significance.

deviation is $10,000, can it be concluded that the average salary
has increased using a 0.02 level of significance?

Yvonne will be graduating in December with a degree in
elementary education. Thanks to her hard work, she already has a
third-grade teaching job lined up after she graduates. It will be
the first time in her life that she will make more than minimum
wage. Because she wasn’t able to make enough money while in
college, she took out student loans to help pay for her education.
She has $15,000 in student loan debt and $3,000 in credit card...
