Section 7 Question 32 2 pts Which of the following statements best describes the differences and/or similarities in general between interval estimation and hypothesis testing? (i) For a 2-tailed test, interval estimation will yield the same result as a hypothesis test. (ii) For a 1-tailed test, interval estimation will yield the same result as a hypothesis test. (iii) For a 1-sided test, interval estimation will not yield the same result as a hypothesis test. (iv) For a 2-tailed test, interval estimation will not yield the same result as a hypothesis test. O (i) and (iii) O (i) and (iv) O (i) and (ii) O all of the aboveSection 8 In order to estimate the effectiveness of thinning, five plots were established in thinned and unthinned stands (on similar sites and in similar forest types). On each plot, the volume increment per year per hectare was measured. The results follow: Volume Increment (m /hectare/year) Thinned Unthinned 8 9 6 4 5 4 10 6 11 2Part 1 Calculate an estimate of the standard deviation (of measured volume increment) in the thinned stand
