lesya692 [45]

Answer:

$34,000

The manager at Food Town estimates that the store sold 325 jars of spaghetti sauce last week. The store actually sold 297 jars o
never [62]

There is a positive, linear relationship between the correct and guessed calories. The guessed  calories for 5 oz. of spaghetti with tomato sauce and the cream-filled snack cake are unusually  high and do not appear to fit the overall pattern displayed for the other foods.  The correlation is r = 0.825 . This agrees with the positive association observed in the plot; it is not closer to 1  because of the unusual guessed calories for spaghetti and cake.  The fact that the guesses are  all higher than the true calorie count does not influence the correlation. The correlation r would  not change if every guess were 100 calories higher. The correlation r does not change if a  constant is added to all values of a variable because the standardized values would be unchanged.  The correlation without these two foods is r = 0.984 . The correlation is closer to 1 because  the relationship is much stronger without these two foods.
