Webb1 juli 2024 · normalcdf (lower value, upper value, mean, standard deviation) For this problem: normalcdf (65,1E99,63,5) = 0.3446. You get 1E99 (= 10 99) by pressing 1, the EE key (a 2nd key) and then 99. Or, you can enter 10^ 99 instead. The number 10 99 is way out in the right tail of the normal curve. We are calculating the area between 65 and 10 99. WebbThe standard deviation is 0.15m, so: 0.45m / 0.15m = 3 standard deviations. So to convert a value to a Standard Score ("z-score"): first subtract the mean, then divide by the Standard Deviation. And doing that is called "Standardizing": We can take any Normal Distribution and convert it to The Standard Normal Distribution. the yard gulf shores alabama
