Question | Answer the question manually without exel An experiment was run to determine whether four specific firing temperatures affect the density of a certain type of brick. The experiment produced the following data 100 degrees 125 degrees 150 degrees 175 degrees 21.8 21.7 21.9 21.9 21.9 21.4 21.8 21.7 21.7 21.5 21.8 21.8 21.6 21.4 21.6 21.4 21.7 21.5 21.5 21.9 a) Estimate the parameters b) State the hypothesis c) Use 0.05 level of significance to test the hypothesis that the mean density of the bricks produced by the different levels of firing temperatures is the same. Discuss the results
