(Click on the image for a larger view.) 12 1 4 8 13 3 7 14 2 6 15 16 (a) To which of the following data sets does this stemplot correspond? OA. 116, 118, 121, 124, 128, 133, 137, 142, 146, 179 B. all integers between 116 and 179 c. 16, 18, 21, 24, 28, 33, 37, 42, 46, 79 D. 1,2,3, 4,6, 6,7,8, 8,9 (b) This stemplot is most similar to O A. a boxplot of the data B. a time plot of the data with the observations taken in increasing order C. a histogram with class intervals between 110 and 120, between 120 and 130, etc. D. reporting the 5-point summary for the data, with the mean. E.None of the above. (c) The lowest score in the class as a percentage of the total possible points is 58Explanation / Answer
Solution:
Part a)
Answer:
A. 116, 118, 121, 124, 128, 133, 137, 142, 146, 179
Explanation:
From given stem plot, for the stem 11, there are two leaves 6 and 8, so number becomes 116 and 118. In the same manner we can find out all numbers from given stem and leaf chart. Numbers at left side are stems and numbers at left side are leaves.
Part b)
Answer:
C. a histogram with class intervals between 110 and 120, between 120 and 130, etc.
Explanation:
We know that the stem plot represent a histogram like nature of the data. For the given stem plot, all stem represent the 10 numbers. For example, stem 11 would represent all numbers between 110 to 119, stem 20 would represent all numbers between 220 to 229, etc.
Part c)
Here, we have to find the lowest score in the class as a percentage of the total possible points.
Total possible points = 200
Lowest score = 116
Required percentage = (116/200)*100 = 0.58*100 = 58%
Required answer = 58%
