Nasa performed aerodynamic and acoustic tests of two and three-dimensional airfoil blade sections. these tests were conducted in an anechoic wind tunnel. one input (x) measured was the free-stream velocity, in meters per second. the output (y ) was scaled sound pressure level, in decibels. from this data, we found the following values: µx = 50.86; µy = 124.8; σxy = 13.44; σx = 15.57; σy = 6.90. (a) find the value of the correlation coefficient to 3 decimals. (b) is the linear relationship / association between x and y strong, weak, or is there no relationship? (c) is there a positive linear relationship, negative linear relationship, or no linear relationship?
