They used 25 baby rats to do the study, and each of them was measured under three different soy percentages (1%, 3.5%, and 5%) What statistical test should they use to test if there is a diference among the average effect of different percentages of soy in the formula? A Dependent samples t-test B: one sample t-test c: one-way ANOVA D: Independent sample t-test 2Which of the following data types may be used in multiple linear regression? Interval or ratio dependent variable Interval or ratio independent variable Dichotomous independent variable All of these are corect. 3 The odds ratio in a logistic regression is 1.3 What does this mean about the odds of the predicted event for each variable? The odds of the predicted event occurring are the same for both variables of the predicted event occurring are greater for one vartiable than the other variables The odds of the predicted event occurring are increased by 130% for both There is not sufficient information to answer the question

Answer 1

1. (c) In this problem, we use One-way ANOVA to test if there is a difference among the average effect of different percentages of soy in the formula.

2. (d) All of these are correct.

3. (a) The odds of the predicted event occurring are the same for both variables.
