(b) To which of the following data sets does this stemplot correspond? A. 1, 2, 3, 4, 6, 6, 7, 8, 8, 9 B. 116, 118, 121, 124, 128, 133, 137, 142, 146, 179 C. 16, 18, 21, 24, 28, 33, 37, 42, 46, 79 D. all integers between 116 and 179 (c) The lowest score in the class as a percentage of the total possible points is %.

Answer 1

a) This stemplot is most similar to

ans-> D) a histogram with class intervals between 110 and 120,between 120 and 130, etc.

b) This stemplot corresponds to -

ans-> B) 116, 118, 121, 124, 128,133, 137, 142,146, 179

c) The lowest score in the class is = 116

The lowest score in the class as a percentage of the total possible points is

116 ann 一半 100

= 58%
