A study conducted by the Center for Population Economics at the University of Chicago studied the birth weights of 799 babies born in New York. The mean weight was 3348 grams with a standard deviation of 874 grams. Assume that birth weight data are approximately bell-shaped. Estimate the number of newborns who weighed between 1600 grams and 5096 grams. Round to the nearest whole number.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
