Question

Define the regression if the raw material used in production of a certain synthetic fiber measurement of the relative humidity the storage location and the moisture content.

Relative Humidity x 0.1×H+1 0.2×H+2 0.3×H+3 0.4×H+4 0.6×H+1 0.7×H+3 Moisture Content y 0.2×H×2 0.3×H×3 0.1×H+1 0.6×H+1 0.7×H+2 0.4×H+3 (a) Plot a graph Y vs. X showing these points or the graph is also called scatter diagram. (b) Calculate ∑ X, ∑ Y, ∑X2 , ∑Y2 , ∑XY, mean of X and mean of Y. (c) Calculate regression equation Y on X. (d) If ? = 82 find the estimated value of Y.
