To solve the problem, we need to find the remaining two observations (let's call them A and B) given the mean and variance of 7 observations, along with 5 known observations. Here’s the step-by-step solution: ### Step 1: Understand the Given Information We know: - Mean of 7 observations = 8 - Variance of 7 observations = 16 - 5 observations = 2, 4, 10, 12, 14 ...
