Kindly solve the following questions correctly

A) What is the effect of an improvement in the country's terms of trade on the equilibrium relative price of tradable goods? What is the intuition behind it? [10 marks] B) What is the effect of an increase in the endowment of tradable goods in period 1 on equilibrium relative prices of non-tradable goods and on the real exchange rate?We continue to consider the use of a logistic regression model to predict the probability of default using income and balance on the Default data set. In particular, we will now compute estimates for the standard errors of the income and balance logistic regression coefficients in two different ways: (1) using the bootstrap, and (2) using the standard formula for computing the standard errors in the gim() function. Do not forget to set a random seed before beginning your analysis. (a) Using the summary() and gim() functions, determine the estimated standard errors for the coefficients associated with income and balance in a multiple logistic regression model that uses both predictors.(b) Write a function, boot.fn(), that takes as input the Default data set as well as an index of the ob- servations, and that outputs the coefficient estimates for income and balance in the multiple logistic regression model. (c) Use the boot() function together with your boot.fo() function to estimate the standard errors of the logistic regression coefficients for income and balance. (d) Comment on the estimated standard errors obtained using the gim() function and using your bootstrap function
