7 The demand function below is estimated using the data generated by a randomized controlled trial:Lng,-a+b'Lnp,+c'Lnpytd*Lnp;tewhere q, is the quantity demanded of the product of interest (X), p, is the price of the product of interest (X), p, is theprice of a substitute product (Y), and p; is the price of a complement product (Z). Also, e is the error term. The table belowshows the 95% confidence interval estimation for parameters b, c, and d:Upper Limit of 95%CIELower Limit of 95%CIE-0.052Parameter-0.031-0.025+0.045-0.154-0.075Choose the correct statement.O Given the estimation results, price of X, price of Y, and price of Z are among the significant determinants of demand for X.O Given the estimation results, price of Y and price of Z are among the significant determinants of demand for X.O Given the estimation results, none of the price measures are among the significant determinants of demand for X.O Given the estimation results, price of X and price of Z are among the significant determinants of demand for XGiven the estimation results, price of X and price of Y are among the significant determinants of demand for X

The Confidence Interval Estimates (CIE) provide the range in which the true value of the population…

In a typical multiple linear regression model where x1 and x2 are non-random regressors, the expected value of the response variable y given x1 and x2 is denoted by E(y | 2,, X2). Build a multiple linear regression model for E (y | *,, *2) such that the value of E(y | x1, X2) may change as the value of x2 changes but the change in the value of E(y | X1, X2) may differ in the value of x1 . How can such a potential difference be tested and estimated statistically?
Compute the sum-of-squares error (SSE) by hand for the given set of data and linear model. (6, 6), (7, 7), (9, 10); y = x − 1
