Question:
 

b.    From the frequency tables for each group, construct a grouped cumulative frequency table for each group.  For each group, construct a grouped cumulative frequency curve from this table.

Answer:

Japanese Participants, Interval Width = 7, 15 Intervals

Score Interval Cumulative Midpoint (X) Frequency (f) Cumulative frequency (cf)
       
133-139 136 2 94
126-132 129 2 92
119-125 122 2 90
112-118 115 0 88
