Suppose that the average cell phone bill at Bellevue University is $38.90 per month with a standard deviation of $3.64 per month. If I take a sample of 44 BU students, what is the probability that the mean amount of their monthly phone bill is greater than $41.00?
Explain in words (4 pts) how you used Excel to find the z-score (2 pts) and probability (2 pts), then attach a screen shot of the two outputs in Excel. Do not just post the Excel output with no explanation, or you will not receive full credit. In addition, be sure you are giving a complete answer rather than showing me your entire Excel spreadsheet with "More Than", "Less Than" etc. on it modeled from the video. I want to know that you can find this in Excel yourself!
For your second post, find the probability that the mean amount of their monthly phone bill differs from the expected mean by more than $1.00, again showing your output and explaining your solution.
