Assume you're using an alpha of 05, and a two-tailed test, to make your decision about whether to reject the null hypothesis. Assume that 18 subjects received one of three treatments and produced the data reported in Data Set B. Conduct a one-way ANOVA to see if the means of the three treatments are different on a statistically significant level. Complete an ANOVA...

You decide to use an alpha level of .05. Based on this, your degrees of freedom, and your hypothesis type (one tailed or two tailed), you determine that your critical region consists of t values greater than or less than . IMPORTANT NOTES: 1. The row with ∞ in the degrees of freedom column is used any time the degrees of freedom exceed 120. 2. Enter your answers to THREE decimal places. If the answer is positive, enter a +...
