1. How would you explain the equivalence of the independent samples t test and one way ANOVA for comparing the means for two groups?

2. What are the important assumptions in ANOVA?

3. When testing a hypothesis for a specific population the test statistic is crucial when trying to calculate a p-value to determine if the null hypothesis can be rejected. If Ha contains a not equal to alternative how exactly do you calculate Z which serves as the standard normal distribution?

4. when the data set contains positive and negative values how will the differentiate the process required to properly calculate the p-value?
