Method 1 is a traditional method of training, and Method 2 is a new and innovative method. The company has just hired 31 new management trainees. 15 of the trainees are randomly selected and assigned to Method 1, and the remaining 16 trainees are assigned to Method 2. After three months of training, the management trainees take a standardized test. The test is designed to evaluate their performance and learning from the training. The sample mean score and sample standard deviation of the two methods are given below. Company management wants to determine whether the company should implement the new training method. What is the alternative hypothesis for this test? A) Ha: μ1 − μ2 = 0 B) Ha: μ1 = μ2 C) Ha: μ1 − μ2 < 0 D) Ha: μ1 − μ2 > 0A researcher wants to see if gender and/or income affect the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affect the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables affected total help if he rejects the null hypothesis. What is one research hypothesis (there are three possible hypotheses here name them all if you can but naming at least one is required)?
