"Live Tree and Tree-Ring Records to Reconstruct the Structural Development of an Old-Growth Douglas Fir/Western Hemlock Stand in the Western Washington Cascades." Corvallis, OR: Forest Science Data Bank, 2005. (a) Obtain a point estimate for the mean and standard deviation diameter of a Douglas fir tree in the western Washington Cascades. (b) Because the sample size is small, we must verify that the data come from a population that is normally distributed and that the data do not contain any outliers. The figures show the normal probability plot and boxplot. The correlation between the tree diameters and expected z-scores is 0.982. Use Option 1 or Option 2 to determine if the…
A sample of human brain volumes (cm3) is given below. Use the given data values to identify the corresponding z scores that are used for a normal quantile plot,then identify the coordinates of each point in the normal quantile plot. a. List the z scores for the normal quantile plot. (Round to two decimal places as needed. Use ascending order.) b. Identify the coordinates of each point in the normal quantile plot. Use ordered pairs for the form (x,y), where x is the sorted human brain volumes in ascending order, and y is the corresponding z score. (Round to two decimal places as needed. Use ascending order.)
