Question

Question 2: |10 Marks You are a consultant assisting a crop scientist in understanding the grain characteristics of peanuts. For each plot under study, at the end of the season, you record, X1=Yield plot weight (kg), X2=Sound mature kernels (gms). You stored the data as esv file in a safe location, however due to a cyber-attack, the original data is lost. Fortunately you have a print copy of mean (44, & ) and variance (0,0%) for each measurements, and the correlation (p) between them. You also notice that the crop scientist prefers to use pounds as the unit of measurement instead of kg, where 1 pound is equal to 0.4535 kilograms. What is the best way of assisting the crop scientist in this adverse situation, by presenting the mean, variances and correlation between measurements?

Answer 1

Glven data; y where I pound = 0:4535 kilograns sát is given that we have lost teh original data and only a print copy of mean, variance and the correlation are available =) from central tendency theory, we know that variance and covariance.. is invariant locations and the mean and standard deviation affected by scale - The mean will change as. per. scale ine, if each observation is multiplied by same quantity. & the mean will in this case, the weight în kilograms will be converted to pounds the value for mean and standard deviation will change. COV(x14) VUCx) * v(4) The numerator change since converted to pounds and denominator also same effect and hence cancelled and the correlation doesn't change The correlation coefficient p in the print out gms Mean of x 2 pounds mean ofy 0:4539) ix=1 gms standard deviation of x 0 g *=441 4 = 42

R 0.4535 pounds standard deviation of y
