Use ANOVA and REGRESSION for the following problems.
1. Divide your data in half, your first 8 observations and your last 7 observations. Then use ANOVA to test to see if there is a significant difference between the two halves of your data.
2. Take your data and arrange it in the order you collected it. Count the total number of observations you have, and label this number N. Then create another set of data starting from one and increasing by one until you reach N. Run a regression using your original set of data as your dependent variable, and your time series as an independent variable.
