Using the sample data, perform one-way analysis of variance (ANOVA). Evaluate whether the average return of at least one of the industry-specific ETFs is significantly different. Use a 5% level of significance.

1. Define the null and alternative hypothesis in mathematical terms and in words.
2. Report the level of significance - 5% or 0.05
3. Include the test statistic and the P-value - test statistic = 55.07; P-value = 0.0
4. Provide your conclusion and interpretation of the test. Should the null hypothesis be rejected? Why or why not?
5. Does a side-by-side boxplot of the 10-year returns of ETFs from the three sectors confirm your conclusion of the hypothesis test? Why or why not?
