Oprah looks at this histogram of a distribution with a mean of 6.7 grams and a standard deviation of 1 gram. She claims that approximately 68% of
the data is between 5.7 and 7.7 grams. What is the error in her thinking?

lol.

it's ok we all do this sometimes.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

7 is the median   7.875 is the mean
