Question

Question 27 0/2.5 A researcher wishes to determine if a person's age is related to the number of hours he or she exercises per week. Data was collected and the output below was generated. Based on the value for r and the scatter plot is linear regression justified in this case? Choose the best response. Simple linear regression results: Dependent Variable: Hours of Exercise Independent Variable: Age Hours of Exercise- 7.3386738-0.10680908 Age Sample size: 6 R (correlation coefficient)- -0.89972239 R-sq 0.80950039 Estimate of error standard deviation: 0.86836684 X) Incorrect

Explanation / Answer

Yes, the linear regression is justified in this case because the value of r (correlation coefficient) is very high, the value of R-sq (goodness of fit value) is greater than 80% and the test statistic for the significance of the correlation test yields a p-value lower than 0.05.
