The following data represent exam scores in a statistics class taught using traditional lecture and a class taught using a pped" classroom Complete parts a through below Traditional 697 69 0 78 5 67 6 85 3 794 56 2 808 80.5 716631 69 8 604 775 125 629 713 770 918 795 77.1 830 69,4 910 782 765 Flipped (b) Which course has more dispersion in exam scores using the sample standard deviation as the measure of dispersion? The The traditional course has a standard deviation of Round to three decimal places as needed ) while the ipped" course has a standard deviation of course has more dispersion c) Suppose the score of 60 4 in tho traditional course was ncorrecty recorded as 604 How does this affect the range? The range is now Type an integer or a decimal Ds not round) How does this affect the standard deviation? The standard deviation is now □ Round to three decimal places as needed What property does this stae? nsert Delete P12 F0 F7 F6 F5 F4

Answer 1

60224 2 77 72 62 71 77 91 79 77 83 69 91 78 76 12345678901 2 3 46 2 95 78 67 85 79 56 80 80 71 63 69 60 91 123456789 10 1 1 1 x

b)

Traditional course has a standard deviation of 8.777 while the flipped ,,,,,standard deviation of 7.985 .the traditional course has more dispersion

c)

range is now 547.8

standard deviation =147.599

option B is correct:Neither the range nor the standard deviation is resistant
