Quizplus · Accepted Answer

Given the significant correlation between age and systolic blood pressure, the best predicted value for y given x = 41 can be estimated by looking at the data provided. The age of 41 directly corresponds to a blood pressure of 120 in the table, making it the best prediction based on the given data.
