9. Why could the mean of the data set below be misleading? ages of teachers: 29.38.39.26. 29. 29. 39. 77.38.29

I think it might be because it’s not in ascending order
Starting from smallest

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.
