In a set of data that is normally distributed, the value that is 1 standard deviation above the mean is 93. the value that is 2 standard deviations below the mean is 39. what is the mean of the set of data? show your work

Dis the solution here

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.
