A sample of n-25 people with a treatment have a mean of M-9.0. The general population has a mean of u=8.5 and standard deviation of o=10. If you did a One-Sample Z-Test, with 2 tails and am.01, and you showed all four steps, which of the following options would correctly match what you got on all four steps? (NOTE: instead of the symbol "u" I will have to use the phrase, "population mean," in the multiple-choice options below). HO: population mean - 8.5; Z-critical - +2.58; Z-obtained - +0.25; Fall to Reject HO O HO: population mean - 9.0; Z-critical - #2.58,25obtained - +2.05; Fall to Reject HO HO: population mean - 9.0: Z-critical - +1.96: Z-obtained - +0.25; Reject HO O Ho: population mean - 8.5: Z-critical - +1.96: Z-obtained - +2.05; Reject HO
