For a data set of chest sizes (distance around chest in inches) and weights (pounds) of six  anesthetized bears that were measured, the linear correlation coefficient is r = 0.854. Use the table available below to find the critical values of r. Based on a comparison of the linear correlation coefficient r and the critical values, what do you conclude about a linear correlation?8. The blood platelet counts of a group of women have a bell-shaped distribution with a mean of  256.1 and a standard deviation of 63.3. (All units are 1000 cells/L.) Using the empirical rule, find each approximate percentage below.a. What is the approximate percentage of women with platelet counts within 3 standard of the mean  or between 66.2,and 446.0 ? b. What is the approximate percentage of women with platelet counts between 192.8 and 319.4 ?
