Amanufacturer of potato chips would like to know whether its bag filling machine works correctly at the 414.0 gram setting. it is believed that the machine is underfilling the bags. a 50 bag sample had a mean of 409.0 grams. a level of significance of 0.01 will be used. state the hypotheses. assume the variance is known to be 169.00.

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.
