You want to determine if diet impacts body weight. You recruit 60 subjects, assigning 20 each to either one of two dietary interventions or to maintain their normal diet. You measure body weight before and after the intervention and calculate the change in body weight (post minus pre weights). Shapiro-Wilk tests show the following: Diet 1 p=0.432, Diet 2 p=0.101, Normal Diet p=0.325. To determine the diet effect on the calculated change in body weight, you would use a Assume all other assumptions are met for a parametric test. Friedman's test One-way repeated measures ANOVA Kruskal-Wallis ANOVA One-way ANOVA
A 2009 study shpwed that handling money reduces the perception of pain. Two groups of participants were asked to participate in a manual dexterity study. Half of the participants were given a stack of blank pieces of paper to count and the other half were given money to count. After the counting task, the participants were asked to dip their hands in 122 degree Farenheit water and rate how uncomfortable it was . The following data shows ratings of pain similar to the results obtained in the study.    Counting Money Counting Paper 7 9 8 11 10 13 6 10 8 11 5 9 7 15 12 14 5 10   A. based on the sample data, does the treatment, does the treatment have a significant effect? Test with a=.01. ( make sure you have ALL the steps involved in a hypothesis test).   B. Calculate Cohens d to estimate the effect size.    C. What a sentence describing the outcome of the hypothesis test and the measure of effect size as it would appear on a research report.
An experiment that was carried out to study how flow rate through a solenoid valve in an automobile's pollution-control system depended on three factors: armature lengths, spring load, and bobbin depth. Four different levels (low, moderate, high, and extreme) of each factor were chosen, and a single observation on flow was made for each combination of levels. The resulting data set consisted of how many observations? Show how you derived your answer.
