- We have to find the LCD of the denominators.
- Then multiply the fraction with the digit obtained from dividing the LCD with the denominator of the fraction concerned.
Here is the work:
LCD of is
.
So we will divide with
and then with
the quotient will further be put into the fraction.
So
will make the fraction
as
.
Similarly
will make the fraction
as
.
Hence with common denominators the fraction can be written as .
Answer:
There is not enough evidence to conclude that average starting salary for clerical employees in the state is less than $35,000 per year.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 35,000 dollars per year
Sample mean, = 34,700 dollars per year
Sample size, n = 100
Alpha, α = 0.10
Population standard deviation, σ = 3,500 dollars per year
First, we design the null and the alternate hypothesis
We use one-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We fail to reject the null hypothesis and accept the null hypothesis.
Thus, there is not enough evidence to conclude that average starting salary for clerical employees in the state is less than $35,000 per year.
