Textbook Question
Chapter 13, Problem 45CE
The manufacturer of Cardio Glide exercise equipment wants to study the relationship between the number of months since the glide was purchased and the time, in hours, the equipment was used last week.
- a. Plot the information on a
scatter diagram . Let hours of exercise be the dependent variable. Comment on the graph. - b. Determine the
correlation coefficient . Interpret. - c. At the .01 significance level, can we conclude that there is a negative association between the variables?

Since no existing treatment exists, they have planned a one-armstudy. They wish to test whether the success rate of the drug is better than 50%, whichthey have defined as the null success rate. Preliminary testing has estimated the successrate of the drug at 55%. The investigators are eager to get the drug into production andwould like to plan for 9 interim analyses (10 analyzes in total) of the data.
