A random sample of 100 observations from a quantitative population produced a sample mean of 21.5 and a sample standard deviation of 8.2. Use the p-value approach to determine whether the population mean is different from 23. Explain your conclusions. (Use α = 0.05.) State the null and alternative hypotheses. H0: μ = 23 versus Ha: μ < 23 H0: μ = 23 versus Ha: μ > 23 H0: μ = 23 versus Ha: μ ≠ 23 H0: μ <...
