Arandom sample of 100 observations from a quantitative population produced a sample mean of 22.8 and a sample standard deviation of 8.3.
use the p-value approach to determine whether the population mean is different from 24.
explain your conclusions. (use α = 0.05.)
state the null and alternative hypotheses. h0: μ = 24 versus ha: μ ≠24 h0: μ = 24 versus ha: μ > 24 h0: μ ≠24 versus ha: μ = 24 h0: μ = 24 versus ha: μ < 24 h0: μ < 24 versus ha: μ > 24
find the test statistic and the p-value. (round your test statistic to two decimal places and your p-value to four decimal places.) z = p-value = state your conclusion.
