Q4 20 Points A particular Rowan tree grows in a wide range of altitudes. Researchers collected samples from 12 trees at different altitudes, and measured the dark respiration rate, expressed as ul of oxygen per hour per mg dry weight of tissue (ul/ hr x mg). The following information gives summary statistics on the data: Altitude Respiration Rate mean 433.333 0.21 std.dev 314.617 0.07771 The thought is the altitude may effect the respiration rate. In addition, we are given that the sample correlation is 0.886665, and SS(resid = 0.013986. (a) Find the 95% confidence interval for the slope. (b) Interpret your confidence interval from (a) in terms of the problem. (c) What linear relationship is suggested by (a), if any? Explain. (d) If the range of altitude was 90 to 790, would it be appropriate to predict a respiration rate at altitude 1500? Explain. (e) Calculate the value of Se, and interpret it in terms of the
