Hey. How do I solve these tasks? Its a mix of differential Equations, integrals and Statistics and Probability.

14) You dme an to determne the e&ct ofa "n concertration Of a Ertilizer on he si ofcabbage (01) *rts. You separate eachplant a plot and appytte Ertilzerto eachplart. The corrertration is between plants. You are irterested on perhrrnirg a IirTar regression Ofthe VFO+1Xj+i, Vj is the si ofthe cabbage platt incrn X i is the amounofferilizer applied tothe plotwhere theplartwas, is an (I.e. the residuaO and BO, 1 are the irtercept and slope coefcients, respectively.Ater gathering you data, calcuhte um of squares ofthe crossprod'ct eqLzIto ssxy= and the sum of br ssxx=410. , even by Given these Wo vaues, calculate vaue Ofthe sbpe 1 . (Hint: check the cha*r on inear regression in the textbook). 15) You have gathered a small dataset Of the number Of flowers produced by a species Of plants in one year. The dataset is given by the sample [10, 22, 42, 18]. where each value is the number of flowers for a different plant. With these data calculate the sample variance for the number of flowers.
