Question

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Find the probability that a given score is between negative 2.02 3.86

The probability is ___

A. A symmetric bell-shaped curve is plotted over a horizontal scale. Two vertical lines run from the scale to the curve. One vertical line is at the labeled coordinate negative 2.02, which is to the left of the curve's center and peak. The other vertical line is at the labeled coordinate 3.86, which is to the right of the curve's center and peak. The area under the curve to the left of the right vertical line is shaded.

B. A symmetric bell-shaped curve is plotted over a horizontal scale. Two vertical lines run from the scale to the curve at labeled coordinates 2.02 and 3.86, which are both to the right of the curve’s center and peak. The area under the curve between the vertical lines is shaded.

C. A symmetric bell-shaped curve is plotted over a horizontal scale. Two vertical lines run from the scale to the curve. One vertical line is at the labeled coordinate negative 2.02, which is to the left of the curve's center and peak. The other vertical line is at the labeled coordinate 3.86, which is to the right of the curve's center and peak. The area under the curve between the vertical lines is shaded.

D. ecactly the same as B but on the left side

OA. O B. O c. OD. 2.02 3.86 2.02 3.86 2.02 3.86 -2.02 3.86 The probability is (Round to four decimal places as needed.) Click to select your answer(s) evo F9 F8 F5 F4 F2 esc Fl

Explanation / Answer

here from above discription option C is correct

here from normal distribution P(-2.02<Z<3.86)=0.9999-0.0217 =0.9783 ( please try 0.9782 if this does not work due to rounding)
