5 Step Hypothesis for Regression
Team D will conduct a test on the hypotheses :
H₀: M₁ ≤ M₂
The null hypothesis states that non-European Union countries (M₁) have a lesser/equal to life expectancy than European Union countries (M₂). H₁: M₁ > M₂
The alternative hypothesis states that non-European Union (M₁) countries have a greater life expectancy than European Union countries (M₂). Team D will conduct research with a level of significance of α = .05 Identify the test statistic: Team D will use the results from our regression analysis to determine whether the slope of the regression line differs significantly from zero. The decision rule is with 95% confidence interval of the 63 sample observations the rejection of the null hypothesis if the computation of the p-value is greater than 2.87 and if the p-value is less than 2.87 the null hypothesis is accepted.

Team D conducted a regression analysis and determined that the p-value of .0299 is less than 2.87 so we will accept the null hypothesis.
