Question

1. An experiment was run to determine whether four specific firing temperatures affect the density of a certain type of brick. A completely randomized experiment led to the following data Temperature Density 100 21.8 21.9 21.7 21.6 125 21.7 21.4 21.5 21.4 150 21.9 21.8 21.8 21.6 175 21.9 21.7 21.8 21.4 (a) Write down the means model associated with this experiment. Please make sure you label all symbols used. b) Write down the null and alternative hypotheses you will test to find out if there is strong evidence to suggest that temperature has a significant effect on mean density. (c) Compute SSTotal, SSTreatment, and SSError and complete the ANOVA table given below. d Test the hypotheses you specified in part (b) ar 005 significance level and state your conclusions

please answer this using SAS program by ANOVA
