The girth {circumference} of a tree is much easier to measure than the height. It is hypothesized that there is a linear relationship between girth {X} and height {'1'}. The following summary statistics were measured of off 31 black cherry trees: height {In feet]I girth {in inches} Fo Further. the estimated regression line is [y hat = 62.113491 + 1.052%], SSE = SSlresidl = 339.564, and r = 0.519 [a]. Find and interpret the value of residual standard deviation is_e}. [b]. Find the 95% condence interval for the slope. and interpret it in terms of the problem. [c]. If the girth of a tree increases by 5 inches, what is the maximum increase in height we could expect on ayerage? Fully explain your answer. [cl] [ERIN Credit] Someone says their tree has a girth of 30 inches. Would you suggest using your linear regression equation to estimate the height of the tree? 1Why or why not? Explain your answer. [Round your answer to three decimal places, x.xxx, if needed]
