- A researcher investigated the relationship between family income and savings. Using data from 15 families, the computed r between income and savings was found to be 0.76. The researcher wants to test if there is a significant relationship between the two variables at 5% level of significance and create a regression equation to predict the possible savings given the income of the family. Interpret the computed r value. Test if there is a significant relationship between the two variables at 5% level of significancearrow_forwardWrite out the regression equation based on the output. What happens to exam performance with every increase in exam anxiety and what do you notice about the standardized regression coefficient (Beta) and the correlation?arrow_forwardHow to write estimated regression equation from coefficient output?arrow_forward
- Why do we have in general, two lines of regression? Obtain the regression of Y on X and X on Y from the following table and estimate the blood pressure when the age is 45. Also give the interpretation.arrow_forwardalso compute two regression equations: (a) an equation in which you predict income using weight as the predictor variable, and (b) an equation in which you predict weight using income as the predictor variablearrow_forwardTrue or False, explain. Suppose two variables are related by the following formula: Z = 57X +3. The t-statistic on the null hypothesis that the slope coefficient is equal to zero will be the same in a regression of Y on X as in a regression of Y on Z.arrow_forward
- 3- Fit full appropriate regression models to study the relationship between the variables. Test the significance of the model and the significance of the regression coefficients at 5% level.arrow_forwardDecide if gender of the students has a significant influence on the relationship between exam 2 and final results. Assume that the intercepts of the models for males and females are the same. Do not test for equality of intercepts. Are the slopes of the relationships between final and exam2 scores difference for males and females? Test on 10% significance. Include complex and simple model, hypotheses, test statistic, pvalue, and final regression equations for men and womenarrow_forwardA study was conducted to determine if a linear relationship exists between Calculus II (Y) grades and Calculus I (X). The researcher found out that the values of the slope and the y-intercept of the regression line is equal to 1.0134 and – 5.239, respectively. What is the predicted Calculus II grade when the Calculus I grade is equal to 85?arrow_forward
- The table below shows the amounts of crude oil (in thousands of barrels per day) produced by a country and the amounts of crude oil (in thousands of barrels per day) imported by a country, for the last seven years. Construct and interpret a 95% prediction interval for the amount of crude oil imported by the this country when the amount of crude oil produced by the country is 5,509 thousand barrels per day.

(Write your interpretation in statement form) Test if there is a significant relationship between the two variables at 5% level of significance (Show complete proof/steps with conclusion in statement form)arrow_forwardThe experimenters conducted a regression analysis on the results and made the output from the analysis publicly available on Open Science Framework (osfio/fm5c2). From this output, we can derive that regression equation shown here. The equation predicts participants' relative performance estimates (from 0% to 99%) from their scores on the measure of their theories of intelligence, while controlling their actual scores on the antoymns test. Remember: The theories of intelligence survey includes a series of statements that participants rate on a scale of 1 to 6; average scores on the overall measure range from 1, indicating views of intelligence as highly stable; to 6, indicating views of intelligence as highly changeable. Relative performance estimate = 12.10 (theories of intelligence score) +0.13 (antonyms test score). Based on this regression equation, what kind of regression analysis did the researchers perform? a. A simple linear regression analysis b. Multiple regression analysis…arrow_forward
