A study was done to look at the relationship between number of lovers college students have had in their detimes and their GPAS. The results of the survey are shown below Lovers GPA 3.3 1.7 3.9 2.3 E B. Find the correlation coefficient: E b. The null and alternative hypotheses for correlation are: The p-value is D D Round to 1 decimal places. Use a level of significance of a=0.05 to state the conclusion of the hypothesis test in the contest of the study There is statistically insignificant evidence to conclude that a student who has had more lovers will have a lower GPA than a student who has had fewer lovers. There is statistically significant evidence to conclude that a student who has had more lovers will have a lower GPA than a student who has had fewer lovers There is statistically significant evidence to conclude that there is a correlation between the number of lovers students have had in their lifetimes and their GPA. Thus, the regression line is useful. There is statistically insignificant evidence to conclude that there is a correlation between the number of lovers students have had in their lifetimes and their GPA. Thus, the use of the repression line is not appropriate. Interpret Round to two decimal places) There is a 83% chance that the regression Une will be a good predictor for GPA based on the number of lovers a student has had. 83% of all students will have the average GPA. Given any group of students who have all had the same number of Lovers, 83% of all of these studetns will have the predicted GPA. There is a large variation in students' GRAS, but if you only look at students who have had a foxed number of lovers, this variation on average is reduced by 33% The equation of the Unear regression line is: Please show your answers to two decimal places) 5. Use the model to predict the GPA of a college student who as had a lovers. GPA Please round your answer to two decimal places.) h. Interpret the slope of the regression line in the context of the question: The slope has no practical meaning since & GPA cannot be negative. For every additional lover students have, their GPA tends to decrease by 0.19. As x goes up, y goes down. L Interpret the y-intercept in the context of the question: If a student has never had a lover, then that student's GPA will be 1.36. The average GFA for all students is predicted to be 1.36. The y-intercept has no practical meaning for this study. The best prediction for the GPA of a student who has never had a lover is 1.36.
