Question: Suppose that at the equator, we can model the noontime temperature in degrees Celsius, Xn, on day n by a sequence of iid Gaussian random

Suppose that at the equator, we can model the noontime temperature in degrees Celsius, Xn, on day n by a sequence of iid Gaussian random variables with expected value 30 degrees and standard deviation of 5 degrees. A new random process Yk = [X2k-1 + X2k]/2 is obtained by averaging the temperature over two days. Is Yk an iid random sequence?
