Lab 6 I. 1. 2. Y has a skewed distribution rather than a uniform distribution. This is not a Normal distribution, because the distribution is not bell-shaped. As the value of Y increases, the bar heights tend to increase. The reason for this is that the square root of a value between 0 and 1 will always be greater than the value itself. Thus, the distribution is shifted toward the right, but it is cut off at 1. 3. The mean of Y is about 0.67, with a standard deviation of

• 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.

Dana University of Pennsylvania ‘17, Course Hero Intern

• 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.
