Hey there, welcome to numerade.
00:03
So we are looking at the amount of waste generated by a person in the metro area.
00:10
So we're given the mean and standard deviation.
00:14
So let's write down these two values, a mean of 3 .7 and a standard deviation of 1 .5.
00:32
All right, so you had to find a probability that a randomly selected person for a area generates around 4 .5 pounds waist daily.
00:46
So this will be the probability the x is between 4 .4 and 5.
01:03
All right.
01:05
So what this probability is equivalent to, so we're going to split this probability into two parts in order to solve this.
01:16
The probability the x is less than five and the probability that x is less than five and the probability that x is less than 4 .4.
01:30
So for both of these probabilities here we would have to set up a z -score equation.
01:41
So let us do 5 first.
01:42
We're going to take the x -value 5 minus into our mean which is 3 .7 divided by our standard deviation of 1 .5...
