Let X be a random variable with mean 18 and variance 8 Let X₁...... Xs be independent random variables that have the same distribution as X. Calculate E[((X₁ + ... + Xs)/5)²] Question 25 1 pts A widget factory makes 10% of its widgets on Monday, 30% of its widgets on Tuesday, and 20% on each of the days Wednesday through Friday.
