A sample of n=40 people with a treatment have a mean of M=131. The general population has a mean of μ=133.5 and standard deviation of σ=5. If you did a One-Sample Z-Test, with 2 tails and α=.05, and you showed all four steps, which of the following options would correctly match what you got on all four steps? H0: population mean = 133.5; Z-critical = ±1.96; Z-obtained = -3.16; Reject H0 H0: population mean = 131; Z-critical = ±1.96; Z-obtained = -0.32; Reject H0 H0: population mean = 131; Z-critical = ±2.58; Z-obtained = -3.16; Fail to Reject H0 Ho: population mean = 133.5; Z-critical = ±2.58; Z-obtained = -0.32; Fail to Reject H0
