Years range from 2012 to 2020. The code below creates the results in the table. year_results = smf.ols(sale_price ~ area + C(year_sold)', data=house_df).fit() print(year_results.summary()) Suppose you run the following and gen the results in the second table hypothesis = 'C(year_sold)[T.2013] = C(year_sold)[T.2014]' t_test = year_results.t_test(hypothesis) How do you interpret the results? O There is statistical evidence that houses sold in 2013 sold for more than houses sold in 2014. O There is no statistically significant difference between the price of a house of the same area sold in 2013 compared to 2014. O There is no statistically significant difference between the price of a house of the same area sold in 2013 compared to 2012. O There is statistical evidence that houses sold in 2013 sold for less than houses sold in 2014
