An industrial psychologist is investigating the effects of different types of motivation on the performance of simulated clerical tasks. The 10 participants in the "individual molivation" sample are told that they will be rewarded accoording to how many tasks they successtully complete. The 10 participauts in the "grup motivation" sample are told that they will be rewarded according \( t \) the average number of tasks completed by all the particapants in their sample. The number of tasks completed by each participant are as follows: Individual Motivation: \( 11,17,14,10,11,15,10,8,12,15 \) Group Mativation: \( 10,15,14,8,9,14,6,7,11,13 \) a. perform a poosed-variances \( + \) test. can you regect the null hypothesis at the \( .05 \) level?
