- Hello, please help me to solve the question (c) and (d) below.Consider this regression model (1) : Yt = β0 + β1 Ut + β2 Vt + β3 Wt + β4 Xt + εt ; where t= 1, ..., 75.We use OLS to estimate the parameters, producing the following model:Ŷt = 1.115 + 0.790 Ut − 0.327 Vt + 0.763 Wt + 0.456 Xt (0.405) (0.178) (0.088) (0.274) (0.017) Given that:R2 = 0.941; Durbin Watson stat DW = 1.907; RSS = 0.0757.(To answer the question, use the 5% level of significance, state clearly H0 and H1 that are tested, the test statistics that are used, and interpret the decisions.) (a) Describe the concepts of unbiasedness and efficiency. State the conditions required of regression (1) in order that the OLS estimators of the model parameters possess these properties. (b) Perform the following tests on the parameters of regression (1): (i) test whether the parameters β1, β2, β3 and β4 are individually statistically significant; (ii) test the overall significance of the regression model;…what is the relationship between an elementary level DFD and a structure diagram? which must be prepared first?(a) An export-ready firm usually does not require success domestically, because international markets are different. True False (b)The three basic steps in the data analysis process are: assess the quality and reliability of the data, sort and classify data, and perform statistical tests and analyze the results. True False (c)The most common technique used when conducting a focus group is brainstorming, by which participants are encouraged to say what comes to mind without thinking too closely about what they are saying. True False (d)Observational analysis is informal, guided discussions in which a small group of potential customers are encouraged to share their views and opinions of an organization, brand, product or service. True False (e) If research objectives cannot be completed using other secondary and primary methods, and if a trip to the target market is required, the travelers should be sure they: gather as much information…
