Interpret the results of the significance test. i The p-value prOVides strong evidence against the null hypothesis. The differences in the infant mortality rates of African, Asian arid Middle Eastern countries is statistically Significant. From a practical perspective. the infant mortality rate in Africa is approximately 2 times the infant mortality rate in the Middle East.
