need assistance with an online Stats Lab / Exam - its is timed 12- 3 pm EST - I have uploaded a practice test to show what it will be like


RAPP1007 Lab Test 1 Practice The data for the test is in the MS-Excel file posted with this test. You are free to use whichever method (e.g., SPSS, MS-Excel) you prefer to complete the calculations. You have one hour and fifty minutes to complete the practice lab test. Unless otherwise stated, for all inferential tests, alpha is set to 0.05. I will take up the exam starting at 2pm. Elite-Level questions have been added. These questions will not be on the test next week. 1. I have investigated stress among Amazon warehouse pickers. For my study I measured job stress by employee Job Classification (Apprentice Picker, Junior Picker, and Senior Picker) and Employee Age (“Under 65” and “65 and older”). a. Complete the appropriate omnibus inferential tests and state your conclusions. b. Complete simple main effects for the factor “Job Classification” c. Where needed, complete Tukey’s HSD d. Elite-Level Question: Complete the following planned comparisons for the “Job Classification” main effect and the “Job Classification” x Employee Age interaction i. Apprentice compared to Junior and Senior Pickers ii. Junior Pickers compared to Senior Pickers 2. I have data on a study that investigated the impact of noise (None, Low, Medium, High noise levels) on task performance for Amazon warehouse pickers. The scores represent the time it took in minutes to pick and package 100 books for shipment. So the higher the time per noise level the poorer the performance. Subjects completed the task for all four noise levels. a. Complete the appropriate inferential test and complete fill in the source table below b. When needed complete post hoc comparisons of means c. Write up your conclusion d. Elite-Level Question: Complete the following planned comparisons i. Noise compared to Low, Medium, and High ii. Low compared to Medium and High iii. Medium compared to High Source SS df MS f f critical Noise Subjects Error Total 3. I plan to complete the following two planned comparisons; P1: Group A and Group B compared to Group C, Group D, and Group E ` P2: Group B compared to Group D and Group E a. State the null hypothesis for both comparisons b. Are the two comparisons orthogonal (independent)? 4. I plan to complete ten pairwise comparisons of means and I have set alpha equal to 0.01. Assuming the null hypothesis is true for all comparisons, what is the probability that I will reject the null hypothesis (commit a type I error) one or more times? 5. I am looking to see if the average number of “Litres of Syrup Sold” differs among the five townships of Severn, Tay, Tiny, Springwater, and Essa. Per township, I collected the “Litres of Syrup Sold” from three farms. Please complete the following tasks (for all tests Alpha equal to 0.05); a. Complete the appropriate inferential test. b. Complete the following planned comparisons i. Severn, Tay, and Tiny compared to Springwater and Essa ii. Severn compared to Tay and Tiny iii. Tay compared to Tiny iv. Springwater compared to Essa b. State your conclusions 6. I have collected running speed data (Miles per Hour) for a sample of Golden Retrievers and Boston Terriers. Are Golden Retrievers faster than Boston Terriers? 7. For a two-tailed independent means t-test with 15 subjects in each group show the following on the diagram to the right; a. The critical value(s) for alpha equal to 0.01 b. Shade in the critical region(s). c. The location of a t-observed equal to 2.80 d.
