0603 Standard Normal Distribution Part 1 Youtube This statistics video tutorial provides a basic introduction into standard normal distributions. it explains how to find the z score given a value of x as w. The histogram of the birthweight of newborn babies in the u.s. displays a bell shape that is typically of the normal distribution: example 2: height of males. the distribution of the height of males in the u.s. is roughly normally distributed with a mean of 70 inches and a standard deviation of 3 inches. Step 1: calculate a z score. to compare sleep duration during and before the lockdown, you convert your lockdown sample mean into a z score using the pre lockdown population mean and standard deviation. a z score of 2.24 means that your sample mean is 2.24 standard deviations greater than the population mean. X − m = 1380 − 1150 = 230. step 2: divide the difference by the standard deviation. sd = 150. z = 230 ÷ 150 = 1.53. the z score for a value of 1380 is 1.53. that means 1380 is 1.53 standard deviations from the mean of your distribution. next, we can find the probability of this score using a z table.
