14. There appears to be some evidence suggesting that earlier retirement may lead to memory decline (Rohwedder & Willis, 2010). The researchers gave a memory test to men and women aged 60-64 in several countries that have different retirement ages. For each country, the researchers recorded the average memory score and the percentage of individuals in the 60-64 age range who were retired. Note that a higher percentage retired indicates a younger retirement age for that country. The following data are similar to the results from the study. Use the data to find the regres- sion equation for predicting memory scores from the percentage of people aged 60-64 who are retired.
