Colin is a student in a consumer mathematics class creating a report on the annual interest rates of savings accounts. He randomly selects 25 brick-and-mortar banks and 25 online banks and then records the annual interest rate for each financial institution. The results of the samples are provided in the accompanying data set. Colin found an interest rate of 2.15% from a brick-and-mortar bank and an online bank. Based on the z-scores you calculated above, for which type of bank is this interest rate a more unusual result, the brick-and- mortar bank or the online bank? Select the correct answer below: The absolute value of the z-score for the brick-and-mortar bank is less than for the online bank, so the brick-and- mortar bank having a 2.15% interest rate is more unusual. The absolute value of the z-score for the brick-and-mortar bank is greater than for the online bank, so the brick- and-mortar bank having a 2.15% interest rate is more unusual. The absolute value of the z-score for the online bank is greater than for the brick-and-mortar bank, so the online bank having a 2.15% interest rate is more unusual. The absolute value of the z-score for the online bank is less than for the brick-and-mortar bank, so the online bank having a 2.15% interest rate is more unusual.
