According to the 2016 Consumer Expenditure Survey, Americans spend an average of $1,124 on cellular phone service annually (U.S. Bureau of Labor Statistics website). Suppose that we wish to determine if there are differences in cellular phone expenditures by age
group. Therefore, samples of 10 consumers were selected for three age groups (1834, 35- 44, 45 and older). The annual expenditure for each person in the sample is provided in the table below.

- You may need to use the appropriate appendix table or technology to answer this question. Individuals filing federal income tax returns prior to March 31 received an average refund of $1,057. Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15). For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience, a population standard deviation of σ = $1,600 may be assumed. What is the test statistic? (Round your answer to two decimal places.) What is the p-value? (Round your answer to four decimal places.) p-value = Find the value of the test statistic. (Round your answer to two decimal places.) State the critical values for the rejection rule. (Use ? = 0.05.
