What is the relationship between the amount of time statistics students study per week and their final exam scores? The results of the survey are shown below. 16 3 4 1 2 73 Time 15 10 3 Score 95 61 67 67 88 90 75 a. Find the correlation coefficient: 1 = Round to 2 decimal places. b. The null and alternative hypotheses for correlation are: H: ?v = o H: ?v + 0 The p-value is: (Round to four decimal places) c. Use a level of significance of a = 0.05 to state the conclusion of the hypothesis test in the context of the study. O There is statistically insignificant evidence to conclude that a student who spends more time studying will score higher on the final exam than a student who spends less time studying. O There is statistically significant evidence to conclude that there is a correlation between the time spent studying and the score on the final exam. Thus, the regression line is useful.
