Answer:
n=64 and n+1=65
Step-by-step explanation:
64 + 65 equals 129
Mean = (8 + 9 + 10 + 16 + 17) / 5 = 60/5 = 12.
x - mean:
8 - 12 = -4, -4² = 16
<span>9 - 12 = -3, -3² = 9
</span>
<span>10 - 12 = -2, -2² = 4
</span>
<span>16- 12 = 4, 4² = 16</span>
<span>17- 12 = -5, -5² = 25
</span>
Sum of the squares = 16 + 9 + 4 + 16 +25 = 70
Variance = 70/5 = 14
Variance = 14
