    1.The following data represent the number of calories per serving and
    the number of grams of sugar per serving for a random sample of high -fiber
    cerals. Here are the data to test this claim.

    Calories, x 200 210 170 190 200 180 210 210 210
    190
    190 200

    Sugar, y 18 23 17 20 18 19 23
    16
    17 12 11 11

    a. Determine the least-squares regression equation from the sample
    data.
    b. Compute the standard error of y'
    c. Compute the standard error of the slope "b" (note y' = a+bx)
    d. Construct a 95% confidence interval about the slope.
