1. The following table gives the estimated stature (length, in cm) of human fetuses at various times (in weeks) since conception. Age_(x) a. b. 18 20 22 24 26 28 30 32 34 36 38 40 Stature_(y) 19.72 23.41 27.80 30.86 33.17 36.27 39.37 41.48 43.51 45.62 48.50 49.81 Find the coefficient of correlation. How closely do the data seem to fit a straight line? Find the equation of the least squares line. C. Plot the data and least squares line on the same graph. Does the line accurately fit the data? d. If this formula continues to be accurate, what would we expect for the stature of a 45-week- old fetus?
