a) A given distribution has a population mean, μ, of 106 and a population standard deviation, σ, of 8. What z-score would be associated with the value x = 140? b) A given distribution has a population mean, μ, of 138 and a population standard deviation, σ, of 11. What z-score would be associated with the value x = 98? c) A given distribution has a population mean, μ, of 143 and a population standard deviation, σ, of 5. Compute the raw, x-value associated with a Z-score of -2.02.
