Case Study: A student measured the stem elongation rate (/ = mm - day ]) of a plant for 10 days grown and obtained the following data. No. of Plant ((/ = mm . day !) Utilize the rules of data approximation. Determine the following: Observations a) arithmetic mean 1 64 b) deviation 69 c) dispersion d) sample standard deviation 64 e) confidence intervals 4 66 f) confidence interval of random error if confidence probability 56 (P) = 0.95 92 g) confidence interval of total error if confidence interval of systematic error ( Ac) = 1 75 h) relative error of the stem elongation measurements 74 LD 69 10 61 Calculations
