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 71.7 69.2 78.7 68.1 84.1 78.5 56.9 81.0 82.0 72.3 63.7 69.0 60.5
Flipped 76.8 72.0 64.0 73.0 78.8 92.5 79.2 77.4 81.8 71.2 91.4 78.5 75.9
(a) Which course has more dispersion in exam scores using the range as the measure of dispersion? The traditional course has a range of 27.2, while the "flipped" course has a range of 28.5. The flipped 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 nothing, while the "flipped" course has a standard deviation of nothing. The ▼ flipped traditional course has more dispersion.

A sample of 10 students record their scores on the final exam
for their statistics class. The mean of the sample is 81 with
sample standard deviation 7 points. Analysis of the 10 sample
values indicated that the population is approximately normal. We
wish to find the 95% confidence interval for the population mean
test scores.
