Question 4. Birthrate (the independent variable) and Female Life Expectancy (the dependent variable) values are given for 10 countries below.

Prepare a scatterplot and briefly discuss the pattern: what sort of a correlation (strength and direction-wise) does the scatterplot suggest?
Calculate the values or r and and interpret these values.

Given here are the data from a dependent variable and two independent variables. The second independent variable is an indicator variable with several categories. Hence, this variable is represented by x2, x3, and x4. How many categories are there for this independent variable? Use a computer to perform a multiple regression analysis on this data to predict y from the x values. Discuss the output and pay particular attention to the dummy variables. y x1 x2 x3 x4 11 1.9...

Given the research questions below, state the independent and dependent variables (or Variable 1 and Variable 2) and level of measurement. Write null and research/alternative hypotheses. Then conduct the appropriate statistical analysis. State tests used, report and interpret key statistics, and explain your findings, including the likelihood you might be committing Type I or II errors given your decision regarding the null hypothesis. Research question is, How and how well age of patients predict how long they take to cure...

4. For the following problems, indicate what the independent variable (IV), dependent variable (DV), null hypothesis (Ho), alternative hypothesis (HA), and the appropriate statistical test would be (t-test for independent samples, t-test for dependent samples, ANOVA). (15 Pts) a. Since muscle tension in the head region is associated with tension headaches, you reason that if you can reduce tension you will reduce headaches. You design an experiment in which 9 subjects with tension headaches participate....
