You go to Dairy Queen for a single serving. Their distribution for single serving is bellshaped with a mean of 8 ounces and a standard deviation of 0.25 oz.
x = s =
Draw the bell-shaped model below, labeling the mean and each standard deviation above and
below the mean.
a. What percentage of servings are between 7.75 oz. and 8.25 oz.?
(think how many standard deviations away from the mean do 7.75 and 8.25 fall?)
b. What percentage of servings are between 7.5 oz. and 8.5 oz.?
(think how many standard deviations away from the mean do 7.5 and 8.5 fall?)
c. What interval contains 99.7% of the servings?
(think how many standard deviations away from the mean does 99.7% of the values fall?)
d. Suppose your serving weighs 8.5 ounces, what percentage of servings are smaller
than yours?
(think where is 8.5 located with respect to the mean?)
