Dataset Location: Use the data set provided to you on our course Blackboard, propellant.csv (with header). Propellant Thrust Data Description: An experiment is conducted to compare four different mixtures of the components oxidizer, binder, and fuel used in the manufacturing of rocket propellant. To compare the four mixtures, five different samples of propellant are prepared from each mixture and readied for testing. Each of five investigators is randomly assigned one sample of each of the four mixtures and asked to measure the propellant thrust. Use significant level a = 0.05.

Important Items:
1. Goal: Construct a Randomized Block Design ANOVA model.
2. Provide descriptive statistics with tables and plots for all variables of interest.
3. Provide any applicable plots or tests.
4. Check the model assumptions for normality and homogeneity of variance.
5. Set up appropriate hypotheses to investigate the effects of the explanatory variables.
Please report statistics summaries for all factor effect.
6. If needed, run a post test for multiple comparisons on the main factor effect.
