continuity. Each point x, is represented by the interval (x-.5, x+.5) and then the normal probabilities are calculated. 4. When we convert normal distributions to the standard normal distribution, we are essentially making them all alike. How is this possible and what are the implications? Normal distributions are bell-shaped and symmetric about their means. When a normal population is standardized, every value is replaced by how many standard deviations above or below the mean that particular value is. So in a normal population with mean 10 and standard deviation 2, the value 12 becomes z=1 and so does the value 14 in a normal population with mean 10 and standard deviation

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
