A random sample of 38 taxpayers claimed an average of $9,507 in medical expenses for the year. Assume the population standard deviation for these deductions was $2,369. Construct confidence intervals to estimate the average deduction for the population with the levels of significance shown below. a. 2% b. 5% c. 20% a. The confidence interval with a 2% level of significance has a lower limit of $ and an upper limit of $ (Round to the nearest dollar as needed.) b. The confidence interval with a 5% level of significance has a lower limit of $ and an upper limit of $ (Round to the nearest dollar as needed.) c. The confidence interval with a 20% level of significance has a lower limit of $ and an upper limit of S (Round to the nearest dollar as needed)
