Answer:
7th-grade: 4.3
8th-grade: 4.5
Step-by-step explanation:
7th-grade and 8th-Grade samples have 20 data points. The mean is obtained adding the values of the data set and dividing this addition by the amount of values.
Mean total household of the 7th-grade sample: (5+4+4+4+4+ 7+ 3+ 4+ 2+ 3+ 4+4+ 2+ 4+ 3+ 8+ 7+ 5+ 4+5)/20 = 4.3
Mean total household of the 8th-grade sample: (7+5+5+5+3+ 4+ 5+ 3+ 2+ 8+
6+5+6+3+3+4+4+5+3+4)/20 = 4.5
