Homework Answers
The mean is 2743.933.
The median is 1769.
Since the mean is greater than the median, the data is skewed to the right.
A right-tailed test will be suitable here since the data is skewed.

My project has to do with the average tuition for in-state
students per semester and the proportion of western states that pay
less than $5000 for tuition. Western states include Alaska,
Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New
Mexico, Oregon, Utah, Washington and Wyoming. I need help with the
best method of graphing this and how to create the confidence
intervals for 95% for BOTH the average tuition for in state
students AND the proportion of western states that...
