The following data represent exam scores in a statistics class taught using traditional lecture and a class taught using a "flipped" classroom. Complete parts (a) through (c) below. Traditional 69.8 69.1 79.6 68.1 85.5 77.7 55.9 80.4 82.0 71.5 63.2 70.7 59.6 Flipped 77.1 70.6 63.2 71.7 78.5 92.1 78.7 76.2 81.0 69.8 92.7 78.2 76.9 (a) Which course has more dispersion in exam scores using the range as the measure of dispersion? The traditional course has a range of 29.6 , while the "flipped" course has a range of 29.5. The traditional course has more dispersion. (Type integers or decimals. Do not round.) (b) Which course has more dispersion in exam scores using the sample standard deviation as the measure of dispersion? The traditional course has a standard deviation of 8.959 , while the "flipped" course has a standard deviation of 8.198. The traditional course has more dispersion. (Round to three decimal places as needed.) (c) Suppose the score of 59.6 in the traditional course was incorrectly recorded as 596. How does this affect the range? The range is now. (Type an integer or a decimal. Do not round.)
