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 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…arrow_forward

- . The National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, seven of them suffered from depression or a depressive illness. If you were conducting a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population, what would the null and alternative hypotheses be?arrow_forwardPART IV: Now, we will return to the complete data set and divide into two new groups: male and female. Consider only the female subjects.1. For these subjects only, construct a stemplot for the variable “age”. (We will be making this into a back-to-back stemplot later, so leave room on the left side.)2. Discuss the shape of your stemplot. Is it symmetric? Positively skewed? Negatively skewed? None of these? Are there any outliers?3. How would you describe the center and the spread of this distribution?4. Find the five-number summary.5. Construct a box plot. PART V: Now, consider only the male subjects. Repeat #1 - #5 from Part IV above for these subjects. For #1, make your stemplot back-to-back with the previous stemplot. For #5, make your boxplots side-by- side.arrow_forwardI want to know solutionsarrow_forward

The researcher sent out an initialsurvey to measure the motivation of a small group of incoming students at the beginning of the semester and a follow-up questionnaire examining their GPA at the end of the semester. Use the following data the researcher gathered to complete each step of the assignment instructions.
