Performing a One-Way ANOVA Test In Exercises 514, (a) identify the claim and state H0 and Ha, (b) find the critical value and identify the rejection region, (c) find the test statistic F, (d) decide whether to reject or fail to reject the null hypothesis, and (e) interpret the decision in the context of the original claim. Assume the samples are random and independent, the populations are normally distributed, and the population variances are equal. If convenient, use technology.Toothpaste The table shows the costs per ounce (in dollars) for a sample oftoothpastes exhibiting very good stain removal, good stain removal, and fairstain removal.
