Assume that women's heights are normally distributed with a mean given by mu equals 63.4 in, and a standard deviation given by
sigma equals 2.4 in. (a) if 1 woman is randomly selected, find the probability that her height is less than 64 in. (b) if 44 women are randomly selected, find the probability that they have a mean height less than 64 in.

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cutoff point with the y axis
We need two points through which the line passes to find the slope:
We found the slope:
So, the equation is of the form:
We substitute a point to find "b":
Finally, the equation is:
