a sample of 50 women is obtained and their heights and pulse rates are measured. the linear correlation coefficient is .242 and the equation regression line is y= 18.5 + .920x .The mean of the 50 heights is 63.4 and the mean of 50 pulse rates is 72.9 beats per min. Find the best predicated pulse rate of a woman who is 69 inches tall. use significance level of a =.05

From the table of critical values for Pearson correlation, we see that the critical value for n = 50,
at 0..05 significance level is 0.279. Since r = .242, there is not a significant correlation...
