43. Data for two quantitative variables was analyzed and the resulting mean of the explanatory variable was 5 in, and the mean of the response variable was 8 Ibs. The standard deviation of the explanatory variable is 2.6 in and the standard deviation of the response is 5.2 lbs. The slope of the LSRL is 1.52 Ibs/in. What is the equation of the least-squares regression line for the standardized values of these two variables? A. 9 = 0.4 + 1.52x B. 9= -7.16 + 1.52x C. D = 0.4 + 0.76x D. 9 = 1.52x E. y = 0.76x
