The Volume In M Ha In A Mature Douglas Fir Stand Was Estimated From 10 Plots Independently By Two Crews Thus Giving P 1 (144.55 KiB) Viewed 47 times

The volume in m³/ha in a mature Douglas-fir stand was estimated from 10 plots independently by two crews (thus giving "paired observations"). Crew #1 consisted of two students in a Monday lab and Crew #2 consisted of two students from a Friday lab. Plot 1 2 3 4 5 6 7 8 9 10 Crew #1 875 959 475 589 925 1200 971 421 892 728 Crew #2 910 878 480 495 1021 980 1002 410 850 620 Answer the following questions (Part 1 to Part 5) using this description. Question 41 Part 2 To find out whether the two estimates are different at 95% confidence level, what tabulated value would you use? Question 42 Part 3 What is the standard error of differences between the two estimates? Question 43 Question 44 1 pts Part 5 Based on your tabulated value in Part 2 and your test statistic in Part 4, is there enough evidence to say that the two estimates differ at alpha -0.05? Part 4 To find out whether the two estimates are different at 95% confidence level, what is the value of the test statistic you obtained? O There is not enough evidence to say that the two estimates differ O There is enough evidence to say that the two estimates differ 1 pts 1 pts 1 pts
