To investigate if online tutoring is as effective (measured by passing rate) as tutoring in person, we collected random samples of students using each of the tutoring method exclusively and performed two statistical analysis (Chi square and correlation). In the outputs, tutor=1 means online, tutor=0 in person, pass =1 means passed a course while 0 means failed. Choose the correct method and report your findings.

A suburban hotel derives its revenue 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. The dataset is a sample of 25 days (Monday through Thursday) from last year showing the restaurant income and the number of rooms occupied. 1) Does the 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. 4) What percent of the variation in revenue in the restaurant is accounted for by the number of rooms occupied?
