Given the data as shown in the table below
x y
56 0.85
44 0.92
68 0.84
76 0.86
94 0.72
a) assuming the correlation coefficient of xx and yy is found to be -0.897995, calculate the slope, mm, and y-intercept, bb, of the "best-fit" line ˆy=mˆx+by^=mx^+b. use 4 decimal places for each of ¯xx¯, ¯yy¯, sxsx, and sysy values obtained from your calculator. round your answer to 4 decimal places.
m=m= .
b=b= .
b) using the equation of the "best-fit" line to predict the value of yy when x=x= 60. enter your answer in 4 decimal places.
ˆy=y^= .
c) using the equation of the "best-fit" line to predict the value of xx when y=y= 0.89. enter your answer in 4 decimal places.
ˆx=x^= .
