Question

The accompanying data are the length in centimeters and girth’s in centimeter of 12 habor seals find the equation of the regression line then construct a scatter plot of the data and draw the regression line then use the regression equation to predict the value of y for each of the given x values if meaningful. If the x value is not meaningful to predict the value of y explain why not

Answer 1

ANSWER:

The data is missing. Kindly follow the steps that I undertook with this data:

	X	Y
	137	107
	168	129
	153	116
	145	105
	160	124
	159	119
	123	104

This gives the scatter plot and the regression equation as well.

Slope : 0.63

Intercept = 19.11
