For this question, there's given table.
00:02
There are 10 values here.
00:04
So, throw a normal probability plot to determine if it is reasonable to conclude the data from the population is normally distributed.
00:11
So for normal distribution, what do we expect? so we expect a linear one here.
00:18
So in order to get the z values, because this is expected z value and the other one, so what we're going to do, we're going to just find the standard division and the mean value.
00:30
Here so when we look at the points here so the mean value is so the first point which is three thousand so we're going to just find the expected graph here so this is 3 ,148 so the mean value is less than this value so that means we're going to have a positive value for this one so the z score would be a positive maybe this is more than some number and what about for the next one so for the next one is 1062 so for 1 ,062 which is close to so this is 10662 and the next one is 743 right and the next one which is 600 63 which is lower value here this is 7073 1 758 and the next one is 3 ,000 3 and the next one is 3 ,000 345 and we have 2 ,011, and the next one is 26, 37, and then we have 1 ,36, 6, and 5.
01:42
So the expected values for this one here, so what we're going to find, the repair cost.
01:49
So when we'll look at the repair cost here, let me just graph the situation here.
01:54
So the first value is 6...
