Question

here is a data set summarized as a stem-and-leaf plot:
5 | 0011233379
6 | 002223333456799
7 | 07889
8 | 189
how many data values are in this data set?
n = 33
what is the minimum value in the last class (at the bottom of the plot)? 81
what is the frequency of the modal class?
frequency =

Explanation:

Step1: Identify classes and their frequencies

Count leaf numbers per stem:

• Stem 5: 9 leaves (0,0,1,2,3,3,3,7,9)
• Stem 6: 14 leaves (0,0,2,2,2,3,3,3,3,4,5,6,7,9,9? Correction: Re-count stem 6 leaves: original text "002223333456799" → 14 leaves (0,0,2,2,2,3,3,3,3,4,5,6,7,9,9 is 15? Wait no: let's list: 0(1),0(2),2(3),2(4),2(5),3(6),3(7),3(8),3(9),4(10),5(11),6(12),7(13),9(14),9(15). Yes 15.
• Stem7:5 leaves (0,7,8,8,9)
• Stem8:3 leaves (1,8,9)

Modal class = class with highest frequency.

Step2: Find modal class frequency

Compare frequencies: 9 (stem5),15(stem6),5(stem7),3(stem8). Highest is 15.

Answer:

15
