son-hours per week.
Tom has one part-time employee who works 20 person-hours per week. Each full-time employee works 404040 person-hours per week.
Write an inequality to determine n, the number of full-time employees Tom may schedule, so that his employees work no more than 260 person-hours per week.
Need inequality and also the graph solution.

Answer:
A normal distribution or z-test is used to construct a confidence interval.
Step-by-step explanation:
We are given the following in the question:
Sample mean, = $3120
Sample size, n = 40
Population standard deviation, σ = $677
The distribution of earnings of college is a normal distribution.
Conditions:
- Since we are given the population standard deviation and the the sample size is also greater than 30.
Conclusion:
Thus, we use a normal distribution or z-test to construct a confidence interval.
