2 5 20g 50g. Any normal distribution can be standardized by converting its values into z scores. It shows you the percent of population.
Around 95 of scores are between 30 and 70.
We work out the probability of an event by first working out the z scores which refer to the distance from the mean in the standard normal curve using the formulas shown. Now for normal distribution graph in excel we have the mean and standard deviation of the given data. It shows you the percent of population. Adjust the accuracy of the machine.
