QUESTION 15 Whenever hypotheses are established such that the alternative hypothesis is "μ > 8", where μ is the population mean, the p-value is the probability of observing a sample mean greater than the observed sample mean assuming that μ = 8. True False QUESTION 16 Whenever hypotheses are established such that the alternative hypothesis is "μ ≠ 8", where μ is the population mean, the hypothesis test would be a two-tailed test. True False QUESTION 17 Which of the following does not need to be known in order to compute the p-value? knowledge of whether the test is one-tailed or two-tailed the value of the test statistic the level of significance None of these alternatives is correct.
