Q9. An industrial psychologist is investigating the effects of different types of motivation on the performance ofsimulated clerical tasks. The 10 participants in the "individual molivation" sample are told that they will be rewardedaccoording to how many tasks they successfully complete. The 10 participauts in the "grup motivation" sample are toldthat they will be rewarded according  the average number of tasks completed by all the particapants in theirsample. 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 V) level?

Let be the population mean number of tasks completed by all the participants in individual…

40 people are randomly sent to walk one of four trails. The time (in minutes) they spend completing each trail is recorded in the table below. (a) Test to see if the times needed to complete a trail vary. Use a 0.05 significance level. (b) Test each pair (A/B, A/C, A/D, B/C, B/D, C/D) to see which trails have a statistically significant difference. Indicate your p-value for each comparison, and when the effect is statistically significant (use 0.05 as your significance level), declare which trail of the two takes more time to complete. Trail A - 30, 33, 41, 27, 36, 31, 37, 40, 29, 35 Trail B - 27, 33, 38, 41, 40, 38, 35, 44, 41, 39 Trail C - 25, 34, 41, 39, 32, 30, 36, 35, 27, 33 Trail D - 41, 39, 46, 37, 40, 42, 50, 42, 50, 33, 47, 43
S A 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her K left hand, and then she asked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it. Among 275 trials, the touch therapists were correct 115 times. Use a 0.01 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective? docx @ Identify the null and alternative hypotheses for this test. Choose the correct answer below. 2 OA.
