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 <...

You would like to estimate the mean price of milk (per gallon) in your city. You select a random sample of prices from different stores. The sample has a mean of 3.60 dollars and a standard deviation of 0.22 dollars. For each of the following sampling scenarios, determine which test statistic is appropriate to use when making inference statements about the population mean. (In the table, Z refers to a variable having a standard normal distribution, and t refers to...
