Please note that this question consists of six parts. You need to show all mathematical calculations to get the final answer. Just giving the answer without showing work may result in zero for the question. Are the means for the final exams same for all statistics class delivery types? Data on the scores on final exams from several randomly selected classes that used the different delivery types – Face-to-Face, Hybrid, Online are obtained. Purpose of the study was to determine whether the average scores on final exams would be the same for all three different delivery types. Research group who conducts the study have decided to use One-way ANOVA to compare the mean scores on final exams. They need help from a statistician to interpret the results. Use provided partial output to answer the following questions. Write down the null and alternative hypotheses for testing whether or not the average scores on final exams would be same for all three different delivery types. Define the parameters and use those defined parameters when you set up null and alternative hypotheses. Compute the degrees of freedom missing in the ANOVA output (i.e. error degrees of freedom) Compute the sum of squares missing in the table (i.e.: Sum of square treatment) Compute the F-value missing in the ANOVA output. At a 5% significant level is there sufficient evidence to claim that the true average scores on final exams are different for at least one of the delivery types. Explain your answer. The output for Tukey pairwise comparisons is given below. Based on the output Is the average final exam scores for Face-to-Face and Hybrid are significantly different? Explain your answer. Which class type seems to have the highest average final exam score?
