Question

Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line.​ (Each pair of variables has a significant​ correlation.) Then use the regression equation to predict the value of y for each of the given​ x-values, if meaningful. The caloric content and the sodium content​ (in milligrams) for 6 beef hot dogs are shown in the table below.

(a) x=160 calories

(b) x=100 calories

(c) x=130 calories

d) x=210 calories

Find the regression equation.

make a correct scatter plot

​(a) Predict the value of y for

xequals=one hundred and sixty

​(b) Predict the value of y for

xequals=one hundred

(c) Predict the value of y for

xequals=130

(d) Predict the value of y for

xequals=210

?

Calories, x	Sodium, y
150	420
180	470
120	320
120	370
70	250
190	550

Answer 1

a) x = 160

y = 72.411 + 2.344 * 160

y = 447.451

b) x = 100

y = 306.811

c) x = 130

y = 377.131

d) x = 210

y = 564.651
