Starting on January 1, we measure the noontime temperature (in degrees Celsius) at Newark Airport every day for one year. This experiment generates a sequence, T(1), T(2), . . . , T(365), of temperature measurements. A simple model (in degrees Celsius) for the daily temperature process Tn is given by

Starting on January 1, we measure the noontime temperature (in degrees Celsius) at Newark Airport every day for one year. This experiment generates a sequence, T(1), T(2), . . . , T(365), of temperature measurements. A simple model (in degrees Celsius) for the daily temperature process Tn is given by 21mm Tn = 16(1 cos(g ) +Xn, where X1,X2, . . . is an iid random sequence of uniform (3, 3) random variables. a. What is E[Tn]? b. Find the autocovariance function CT [11, k]. c. Why is this model overly simple
