1. Thirty six subjects are randomly assigned to one of twelve groups in a study investigating the separate and joint effects of imagery instruction and imagery vividness on recall. Four kinds of imagery instruction (passive, active, reactive, and control) and three kinds of imagery vividness (low, medium, and high) are used. Following treatment, all subjects are given a 30-item recall test, yielding the following data: Control Passive Active Reactive Low Med High Low Med High Low Med High Low Med High 4 5 7 39 10 5 13 22 5 79 59 18 4 11 19 4 13 17 5 9 14 4812 6 14 24 5 6 11 3 15 26 a) Fill out a complete 2-way ANOVA table and determine if the main effects for imagery instruction and imagery vividness, and the instruction x vividness interaction, are significant (each with a ≤.05). b) If a main effect for imagery vividness is found, perform Tukey post hoc tests to determine which means differ from one another.

A class of undergraduate mechanical engineering students was surveyed. Respondents were asked about their political alignment. Of the 340 students who answered that question, 45 declared being conservative, 126 aligned with liberal ideology and 169 saw themselves as moderate. i) Give a frequency table for these data on political alignment. ii) Show how to obtain the corresponding relative frequency distribution and write a short sentence describing it. iii) How many modes do you see? What might explain this? iv) Is the shape symmetric, skewed right or left? What might explain this? Finally, in that same survey, respondents were asked to pick a random number from 1 to 9. v) What type of shape do you expect to see for a histogram displaying their answers and why?

Base on the same given data uploaded in module 4, will you conclude that the number of bathroom of houses is a significant factor for house price? I your answer is affirmative, you need to explain how the number of bathroom influences the house price, using a post hoc procedure. (Please treat number of bathrooms as a categorical variable in this analysis) Base on the same given data, conduct an analysis for the variable sale price to see if sale price is influenced by living area. Summarize your finding including all regular steps for your method. Also, will you conclude that larger house corresponding to higher price (justify)?
