Coursework for Data Analysis - Essay ExampleGrowth the coefficient for growth is given up as 0.48663, this means that there is a positive relationship amongst growth and vote and as such for every unit of measurement increase in the growth, the low-level variable (vote) increases by a factor of 0.48663 and vice versa.Goodnews the coefficient for goodnews is given as 0.64031, this means that there is a positive relationship betwixt goodnews and vote and as such for every unit increase in the goodnews, the dependent variable (vote) increases by a factor of 0.64031 and vice versa.War the coefficient for the war is given as -2.66658, this means that there is a negative relationship between war and vote and as such for every unit increase in the war, the dependent variable (vote) decreases by a factor of 2.66658 and vice versa. psyche the coefficient for person is given as 3.04593, this means that there is a positive relationship between person and vote and as such for every unit inc rease in the person, the dependent variable (vote) increases by a factor of 3.04593 and vice versa.b) Perform tests for the statistical significance of the parameters of the independent variables inflation, growth and goodnews using the precise value of the corresponding t-distribution and the test p-value. Interpret the tests results.Inflation the computed t-distribution is given as -1.37 whose -1.37 is 1.37 a value less than the critical value of 2.0423, meaning that we fail to close out the worthless hypothesis. Similarly using the p-value we get that the p-value is 0.1830.05 (significance level), leading us to accept the null hypothesis and thus concluding that the parameter of inflation is insignificant in the model at 5% significance level.growth the computed t-distribution is given as 3.03 a value greater than the critical value of 2.0423, meaning that we reject the null hypothesis. Similarly using the p-value we get that the p-value is 0.006
