QuestionHere is a data set summarized as a stem-and-leaf plot:  4# 123346785#00013555666777777 6# 03778 7# 268\begin{array}{l|l} \text { 4\# } & 12334678 \\ 5 \# & 00013555666777777 \\ \text { 6\# } & 03778 \\ \text { 7\# } & 268 \end{array}
How many data values are in this data set? n=n= \square What is the minimum value in the last class? ans == \square What is the frequency of the modal class? (Hint, the modal class is the one with the most observations in it. How many observations are in that class?) frequency == \square How many of the original values are greater than 60 ? ans == \square

Studdy Solution
Count the number of values greater than 60. This includes all values with stems of 6 and 7.
From the stem-and-leaf plot: - Stem 6 has 5 values. - Stem 7 has 3 values.
Total values greater than 60:
5+3=85 + 3 = 8
Total number of data values: n=33Minimum value in the last class: ans=72Frequency of the modal class: frequency=17Number of values greater than 60: ans=8\begin{array}{l} \text{Total number of data values: } n = 33 \\ \text{Minimum value in the last class: } \text{ans} = 72 \\ \text{Frequency of the modal class: } \text{frequency} = 17 \\ \text{Number of values greater than 60: } \text{ans} = 8 \end{array}
