A variable has a mean of 100 and a standard deviation of 32. Sixteen observations of this variable have a mean of 108 and a sample standard deviation of 36. Determine the observed value of the a. standardized version of x.
b. studentized version of x.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
