Question

A certain group of test subjects had pulse rates wth a mean of 77-5 beats per minute and a standard deviation of 10.1 beats per minute. Would t be unusual for one of the test subjects to have a puse rate of 147.7 beats per minudte? Minimum usuar value = beats per minute (Type an integer or a decimal.) Maximum "usual" value = | | beats per minute Type an integer or a decimal.) Is 147.7 beats per minute an unusual pulse rate? A. Yes, because it is between the minimum and maximum "usual values O B. No, because i m and maximum "usual values O C. Yes because it is larger than the maximum "usuar value O D. No, because it is larger than the maximum "usuar value O E. Yes, because it is smaller than the minimum "usual" value O F No, because it is smaller than the minimum "usuar value it is between the minim

Explanation / Answer

= 77.5

= 10.1

Minimum usual value = - 2* = 77.5 - 2*10.1 = 57.3

Maximum usual value = + 2* = 77.5 + 2*10.1 = 97.7

Option-C) Yes, because it is larger than the maximum usual value.
