Mary wants to see if she can predict the number of volunteer hours that potential volunteers will provide, if she has information on the volunteer's income level. If Mary collects information on volunteer hours from her volunteers as well as their income level rounded to the nearest dollar, what statistical application could she use in order to see if income level can accurately predict the number of volunteer hours a potential volunteer may provide? Remember Mary doesn't just want to know about correlation, Mary wants to be able to predict the exact number of hours a volunteer is likley to give. Which data collection is correct?

Pearson's R
Kendall's Tau C
Chi Square
Simple Regression
