Suppose we are comparing the average monthly grocery expenditures (in dollars) for households in three different regions. Independent random samples of size $6$ were taken from each region. The computed test statistic is $F=1.07$ for testing whether the mean monthly grocery expenditure differs between the three regions. Assume the populations are normally distributed and the population variances are equal. Use a significance level of $\alpha =0.10$. What conclusion can be drawn about the mean monthly grocery expenditures across the three regions?

• A. There is insufficient evidence to conclude that the mean monthly grocery expenditures differ between the three regions
• B. There is sufficient evidence to conclude that the mean monthly grocery expenditures differ between the three regions

Answer: (A)
