A suburban hotel derives its gross income from its hotel and restaurant operations. The owners are interested in the relationship between the number of rooms occupied on a nightly basis and the revenue per day in the restaurant. Below is a sample of 25 days (Monday through Thursday) from last year showing the restaurant income and number of room occupied.

Use a statistical software package to answer the following questions.

1. Does the breakfast revenue seem to increase as the number of occupied rooms increases? Draw a scatter diagram to support your conclusion.
2. Determine the correlation coefficient between the two variables. Interpret the value.
3. Is it reasonable to conclude that there is a positive relationship between revenue and occupied rooms? Use the .10 significance level.
