Question

In a recent year, the total scores for a certain standardized test were normally distributed, with a mean of 500 and a standard deviation of 10.3. Find the probability that a randomly selected medical student who took the test had a total score that was more than 527 The probability that a randomly selected medical student who took the test had a total score that was more than 527 is (Round to four decimal places as needed.)

Answer 1

S + Answer) Mean (M)=500 standard deviation (0) 2 10.3 P (score more than 527) 2 P ( x 827) 2?810 first converting into a-score; z za- u 527- Soo 27 2.62 2 10.3 10.3 so, plx>57). p(2>2.62) 1- plz (2.62) has z-table 2 gives area to the legt) 2 1-0.9956 2 0.0044

I have used z table to find z values.

In the above image P stands for probability.

The final answer is boxed.

Hope this helps you !!!
