Question: (d) (2 points) Fix a sample size no = . For each of the group means i, we define a binary random variable Zi: Zi

(d) (2 points) Fix a sample size no = . For each of the group means i, we define a binary random variable Zi: Zi = 1(15() - 1/ Z E). In other words, Z; is 1 if the corresponding group mean is close to the true mean / (within E), and 0 otherwise. Show that E[Zi]
