Use the calculator displays to the right to make a decision to reject or fail to reject the null hypothesis at a significance level of α=0.01. (View the image for the displays)   The correct answer is.. A. Since the​ P-value is greater than α​, fail to reject the null hypothesis. B. Since the​ P-value is greater than α​, reject the null hypothesis. C. Since the​ P-value is less than α​, fail to reject the null hypothesis. D. Since the​ P-value is less than α​, reject the null hypothesis.

Please only answer PART B

A test was given to a statistics class. Results for each gender and for one student in each gender are given. From the information provided, determine which student received a relatively higher grade. The female scored a 77 with μ=79 and σ=3. The male scored a 85 with μ=87 and σ=2. Both students have the same relative grade The female student has a higher relative grade than the male student The male student has a higher relative grade than the female student Not enough information to determine

Read through this scenario and look at the data that was collected.  State the null and all possible research hypotheses.  Review the results below (I used SPSS) and answer the questions that follow. Scenario:  A researcher wants to see if gender and / or income affects 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 - affects 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…
