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.

...The five-step processes for hypothesis testing are the following.
Step1. Specify the null hypothesis H0 and alternative hypothesis H1. The null hypothesis is the hypothesis that the researcher formulates and proceeds to test. If the null hypothesis is rejected after the test, the hypothesis to be accepted is called the alternative hypothesis. For example if...
