![]() ![]() Is that above the mean? Well, they tell us that Minus 150 is equal to, we coulda done that in our ![]() To tell us what proportion is less than that amount Many standard deviations he is above the mean, that's our z score, we can look at a z table The standard deviation is and we know the difference between Darnell's heightĪnd the mean height, and then once we know how Many standard deviations above the mean is Darnell,Īnd we can do that because they tell us what That will give us the proportion that are lower than Darnell's height. So, we wanna figure out what is the area under the normal curve right over here. Proportion of students' heights are lower than Darnell's height. So, Darnell is above the mean, so let's say he is right over here, and I'm not drawing itĮxactly, but you get the idea. They tell us that there's a standard deviation of 20 centimeters and Darnell has a height There's a mean of 150Ĭentimeters, so right over here. So, they're saying that heightsĪre normally distributed. What proportion of student heights are lower than Darnell's height? So, let's think about Darnell is a middle school school student with a height of 161.4 centimeters. School students' heights are normally distributed withĪ mean of 150 centimesters and a standard deviation
