So this first one is for the variable m. And so right here in the middle, that is the mean of m. And we know that this is going to be equal to 178 centimeters. We'll assume everything is in centimeters. We also know that it has a standard deviation of eight centimeters. So for example, if this is one standard deviation above, this is one standard deviation below, this point right over here would be eight centimeters more than 178, so that would be 186. And this would be eight centimeters below that, so this would be 170 centimeters. So this is for the random variable m. Now let's think about the random variable w. The random variable w, the mean of w, they tell us, is 170. And one standard deviation above the mean is going to be six centimeters above the mean.
