1.7. A study was conducted to analyse the effect of the size of the deposit level (X₂) and the likelihood that a returnable one-litre bottle will be returned. A return of a bottle recorded as Y = 1and no return Y = 0 was recorded. Use the following table to do a Pearson Chi-Square Goodness of Fit test in order to detect major departures from the logistic response function. That is that the logistic regression is a good fit for the data. ft = [1 + exp(2.077 -0.136X]-¹ Use x²(0.99,df) = 6.63 for a = 0.01, and determine the df-value. j- 2 3 10 15 300 300 80 126 nj Y₁ Complete the following table: ji 1 2 3 لي 1 2 300 50 4 TT₁ P₁ = Y/n Ojo not ret Ejo not ret n-Eji ret 22 300 150 0j1 ret Chi Square= Ej1 ret = 12+ T Totals Totals E (Ojo - Ejo)² Ejo Totals E₁ (0₁₁ - Ej₁)² Ej₁
