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.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
