A fаctоry mоnitоrs the diаmeter of shаfts using an EWMA chart. The target mean is μ0=50mu_0 = 50, the process standard deviation is σ=0.5sigma = 0.5, and the smoothing constant is λ=0.2lambda = 0.2. The EWMA statistic is calculated using: Zi=λXi+(1−λ)Zi−1, Z0=μ0Z_i = lambda X_i + (1 - lambda) Z_{i-1}, quad Z_0 = mu_0 The first two sample measurements are: X1=50.4,X2=50.6X_1 = 50.4, quad X_2 = 50.6 Question: What is the value of Z2Z_2 (the EWMA statistic for the second sample)?
