QUESTION 1

This comes from Lesson 2. There are three questions about this situation.

On an episode of Andy Griffith, Goober decides to increase business at the filling station with a raffle, but he makes a big mistake. This is not the accurate numbers, but a similar idea. Let's say Goober has 100 tickets printed, as shown follows:

1- One ticket wins $50

2- Two tickets win $20 each

3- Five tickets win $10 each

4- 42 tickets win $1

5- The rest just get a happy face and no money.

What is the probability of winning something for a customer who gets one ticket? Give your answer as a percent. Show how you got your answer.

QUESTION 4

This comes from Lesson 5. There are four questions using this data.

1- Keeping in mind that there are TWO good ways to compute the midpoint of a class interval and we will only do it one way, find the value that should go into cell C4.___________

2- Find the correct value for cell D6.___________

3- The Excel formula that would best compute the value in Cell B9 is__________ and the Excel formula that would best compute the value in Cell D3 is_________

4- Compute the mean of this grouped data. If needed, round to the nearest 0.01. To get full credit, the answer must be exact to the nearest hundredth. Partial credit given by the instructor for rounding error.______________
