Question

A selection of cereals was sampled and the number of calories was plotted against the number of grams of protein with the following results:




Which of the following is NOT CORRECT?

		The regression line is y-hat = 106.0 + .339(protein)
		Cereals with 5 grams of protein are estimated to have 106.99 calories/serving.
		Each additional gram of protein increase the estimated calorie content per serving by .339 calories.
		The slope is 0.339.
		It is estimated that cereals with no protein would have 106 calories/serving.

Answer 1

As equation is: y-hat = 106.0 + 0.339(protein)

Hence, 0.339 is the slope here and it indicates that Each additional gram of protein increase the estimated calorie content per serving by .339 calories.

y-intercept is 106.0 which shows that cereals with no protein would have 106 calories/servings.

So, these 3 statements are ture.

Hence, Option A) Cerealz with 5 grams of protein are estimated to have 106.99 calories/serving is not correct.

So, Option A) is the answer.
