On page 539, we discussed how to use summary statistics (sample sizes, sample means, and sample standard deviations) to conduct a one-way ANOVA.
a. Verify the formula presented there for obtaining the mean of all the observations, namely,
b. Show that, if all the sample sizes are equal, then the mean of all the observations is just the mean of the sample means.
c. Explain in detail how to obtain the value of the F-statistic from the summary statistics.
Fill in the missing entries in the partially completed one-way ANOVA tables.
