Step-by-step explanation:
1. Number of absent students:
0,1,1,0,3,2,5,1,9,0
Find the:
Mean
0, 0, 0, 1, 1, 1, 2, 3, 5, 9/10
= 22/10
= 2.2
Median
0, 0, 0, 1), 1, 1, (2, 3, 5, 9
= 1 + 1/2
= 2/2
= 1
Lower quartile
Upper quartile
Range
= 9 - 0
= 9
Interquartile range = 3
Mean absolute deviation = 2.08
Standard deviation = 2.71
715=448+(3x)
715-448=3x
267=3x
267/3=x
89=x
