The traditional course has a range of 29.5 , while the "flipped" course has a range of 29.4 . The traditional course has more dispersion. (Type integers or decimals. Do not round.)

The traditional course has a standard deviation of 8.846 , while the "flipped" course has a standard deviation of 7.899 . The traditional course has more dispersion. (Round to three decimal places as needed.) (c) Suppose the score of 60.5 in the traditional course was incorrectly recorded as 605. How does this affect the range? The range is now 549.1. (Type an integer or a decimal. Do not round.) How does this affect the standard deviation? The standard deviation is now (Round to three decimal places as needed.)
