15) A colleague who has not taken the PSYC 2127 course, but only 2126 (let's say... Stphanie...) comes to see you in crisis. She works as a research assistant for a professor. She was to use the SPSS statistics program to calculate ANOVAs. She doesn't understand scans, she just learned which buttons to press. However, there was a power failure when she was printing the results. She doesn't know what to do because she lost most of the document; she managed to print just part of the scan. Task descriptive statistics Mean Standard deviation N 1 .7000 .13858 32 2 .5647 .18182 32 3 .6125 .14835 32 4 .6120 .11806 32 Total .6223 .15472 128 Inferential statistics SC dl CM F Processing 0.306 Error 2.734 Total As you can see, the independent variable has 4 levels and each group is made up of 32 individuals. Since you've learned to do the math and not just press buttons, reassure her and tell her you can help!

a) On the one hand, since you do not have the details of the research question, show him how to write the null hypothesis in symbols. (2 points)

b) i. On the other hand, show him how to write an alternative hypothesis in symbols. (2 points)

ii. There is more than one possibility for the alternative hypothesis. Explain why. (4 points)

c) Use the appropriate steps to complete each of the boxes on the poorly printed table and present all of your calculations and formulas. (20 points)

d) What is the decision about the results? (3 points)

e) What should she do next? In other words, now that it has its analysis of variance, are there any other steps that will need to be done and why? (Be specific and give a full answer.) (8 points)

f) If in the previous question you said there are other steps to take, do them. Show all of your calculations and formulas. (11 points)

g) Present your results scientifically. (4 points)

h) Interpret your results. What would you say to the researcher? (2 points)
