One Sample Hypothesis 2
Sample Hypothesis Testing Paper
Baby boomers are reuniting with the education world. The economy had a major
downturn, which cost thousands of Americans to enter a non-working status quo. Many years
ago, it was not what an individual knew, to gain a position of employment; it was who the
individual knew to obtain a decent paying job. Education was not a major influence on obtaining
a position of employment, which would increase his or her income. Unfortunately,
unemployment is forcing organizations to seek a high qualifying staff with a higher education.
Employers are looking for individuals with higher education to grow with the company and
become an asset to the future of the company’s organization. This demand proves that education
has an influence on individuals’ wages. Individuals needing to make an income to prove for his
or her living accommodations, is in need of returning to college to further his or her education.
The preliminary data shows that most individuals making over $40,000 per year attended
school 12+ years, only a few of the individuals had fewer than seven years of education under his
or her belt. The study further shows that the work experience for the individuals who returned to
college were in a range from five to 44 years in age. In contrast, individuals who attend school
for fewer than 12 years are making less than $40,000 per year, whereas most individuals are not
making a large amount of money, his or her experience ranges from 19 years to 54 years.
Purpose of Research
In addition to education, several other factors contributing to individuals earning a higher
or lesser wage at the same positions. Those factors include race, age, ethnicity and work
experience. Individuals with long history of work experience will be an asset to the company and
will in turn make a larger wage than a person newly entering the industry. Our team will try to

determine how these factors come into play. The team will also determine how they affect
various groups and their ability to attain a high paying job.
Definition of Problem
The ability to earn a higher wage tends to be dependent on the level of education one
receives. Our charge will be to determine if the studies are correct in showing that individuals
attending school for more than 12 years is more apt to receive a higher wage in the same type of
position. The data provided below will assist the team during the research process and will help
determine whether or not the team should reject the null hypothesis indicating that those
individual attending school for more than 12 years will earn a higher wage.
Hypothesis Statement Formulated
H
0
µ ≥ .50 – individuals with a college degree or higher earns 50% more in wages
H
1
µ < .50 = individuals with less than a college degree earn 50% less in wages
Five-Step Hypothesis Testing
Our five-step hypothesis test will be formulated as follows and will help us demonstrate
the effects a college degree may have on one’s ability to earn higher wages:
Step 1
Null hypothesis: H
0
:
µ
≥ .50
Alternate hypothesis: H
1
:
µ
<.50
