0.53, right over there, and we just now have to figure out what value gives us a z-score of 0.53. Well, this just means 0.53 standard deviations above the mean. So to get the value, we would take our mean, and we would add 0.53 standard deviation, so 0.53 times nine, and this will get us 0.53 times nine is equal to 4.77, plus 80 is equal to 84.77. 84.77, and they want us to round to the nearest whole number. So we will just round to 85 beats per minute. So that's the threshold. If you have that resting heartbeat, then the school nurse is going to give you some additional screening.
