PLEASE help me to answer following questions.

3. (42 pts) The taste of cheese is related to the concentration of several chemicals in the final product. In a study of cheddar cheese, samples of cheese were analyzed for their chemical composition and were subjected to taste tests. The variables studied were as follows: Y: Taste test score (Taste) X1: Log-transformed concentration of hydrogen sulfide (H2S) X2: Concentration of lactic acid (Lactic) X3: Log-transformed concentration of acetic acid (Acetic) Three models were fitted using SPSS.

Interpret the coefficient in the context of the problem. Does the model provide an adequate fit according to this measure?c. (6 pts) Test if Model 3 is significant overall. Clearly state the null and alternative hypotheses in terms of the regression coefficients.f. (6 pts) Consider Model 2, use Bonferroni procedure to find the 90% family confidence interval of B, and B2
