For the data below, compute the Pearson correlation. 4 6. Find coefficient of determination: 5. 2....
5. Calculating the Pearson correlation and the coefficient of determinationSuppose you are interested in seeing whether the total number of days students are absent from high school correlates with their grades. You obtain school records that list the total absences and average grades (on a percentage scale) for 80 graduating seniors.You decide to use the computational formula to calculate the Pearson correlation between the total number of absences and average grades. To do so, you call the total number of...

Find the value of the coefficient of determination. The table below gives the list price and the number of bids received for five randomly selected items sold through online auctions. Using this data, consider the equation of the regression line. bo + bjt, for predicting the number of bids an item will receive based on the list price. Keep in mind. the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would...
