8. A researcher conducts a hypothesis test with a non-directional alternative (two-sided test) and calculates the p-value. If the researcher had decided to do a hypothesis test with the same data but with a directional alternative (one-sided test), how would have the resulting p-value compared? (Hint: don't forget about checking directionality.) The p-value of the one sided test would have been smaller than the p-value of the two-sided test. The p-value of the one sided test would have been larger than the p-value of the two-sided test. It would depend on the direction of the alternative hypothesis; the resulting p-value could be smaller or larger. The entire test would need to be done again to find the p-value. 9. A manufacturer of PVC pipes wants to make sure that the parts meet their quality standards. If the pipes are supposed to have an opening with a diameter of exactly 11.0 mm, what set of hypotheses would the manufacturer use to make sure their pipes are acceptable? Ho: 11.0, HA : H= 11.0 Ho : u = 11.0, HA : > 11.0 Ho : u = 11.0, HA: 4 11.0, HA :μ
