Use "tur gdp-un-inf.rds" data for this exercise. It is available under Resources in itslearning. Regress Turkish unemployment rate (un) on Turkish GDP growth (gdp gr). un=B0+B1gdpgr+u This is known as Okun's Law. Estimate B0(Beta0) and B1 (beta1) using R manually and using function in R. Report how much of the variation in unemployment rate is explained by GDP growth and this model. Answer also other additional questions below. Number of observations in the data set is Number of variables in the data set is beta0_hat is equal to beta1_hat is equal to percent of variation in unemployment rate is explained by this model.
