<p>Hey can somebody please answer this Stat question for me?</p>

<p>The mean blood pressure for 47 year-old males in the United States is 138 mg with a standard deviation of 25 mg. A doctor tells his 47 year-old male patient he is in the lowest 10% of all people in this population. What is the range of values that this patient falls in?</p>

<p>Thanks :)</p>

<p>find the z score that you get the 10% in then use ure calculator to figure out the value from -10 to that?. took stats last year pretty sure this is right</p>
