(a) Which course has more dispersion in exam scores using the range as the measure of dispersion'? The traditional course has a range ofwhile the "Tipped" course has a range of The Type integers or decimals. Do not round.) course has more dispersion.
(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, while the "flipped" course has a standard deviation of. The (Round to three decimal places as needed.) course has more dispersion.
(c) Suppose the score of 59.1 in the traditional course was incorrectly recorded as 591. How does this affect the range?
