Assume that women's heights are normally distributed with a mean given by h = 62.3 in, and a standard deviation given by 0 = 3.1 in. (a) If 1 woman is randomly selected, find the probability that her height is less than 63 in.
(b) If 49 women are randomly selected, find the probability that they have a mean height less than 63 in.
(a) The probability is approximately
(Round to four decimal places as needed.)

step-by-step explanation:

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.
