Calculator Note 11B: Augmenting a List The augment command can speed up your work on Activity 11.1b. For example, for Case 1 in Activity 11.1b, first define list L 1 as {0, 0, 0, 0, 1, 1, 1, 1}. Define list L 2 as randNorm(10,3,4) —four random values from a normal distribution with mean 10 and standard deviation 3. Similarly define list L 3 as randNorm(12,3,4).

    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.
