The mean output of a certain type of amplifier is 129 watts with a standard deviation of 11 watts. If 70 amplifiers are sampled, what is the probability that the mean of the sample would differ from the population mean by more than 0.6 watts? Round your answer to four decimal places.

I really need these points thx a lot

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.
