One professor was interested in evaluating the overall performance of students in online sections. He wanted to know if students in an online section would do as well as students in a face-to-face section. So one semester he has the same class but one class was delivered in an online format and one section was delivered face-to-face and it served as a control section The grades of each section are listed below ,with 4.0=A down to 0.0=F A. Write out in words the Null and Alternative hypotheses for this situation B.Create a histogram of each class using the bins below. C.What is the correct statistical test to use satistically determine if there is a difference between the delivery methods. Perform the correct Test,highlight the result you use to interpret the test and report in words your conclusion about the hypothesis E. How do these results compare?Practically, what is happening in the classes?

The following data is based on information taken from Winter Wind Studies in Rocky Mountain National Park by D. E. Glidden (Rocky Mountain Nature Association). At five weather stations on Trail Ridge Road in Rocky Mountain National Park, the peak wind gusts (in miles per hour) for January and April are recorded below:

Does this information indicate that peak wind gusts are higher in January than in April? Use a .03 significance level. Please use the four step process and round your answers to the nearest fourth decimal place.
