Answer:
2.42
Step-by-step explanation:
standard deviation= sqrt(variance)
Variance=E[X2] - E[X]2
E[X] = sum(X)/n=35/9, so E[X]2 = 1225/81
E[X2] =sum(X2)/n = 189/9 = 170/81
Variance= 476/81
Standard deviation = sqrt(476/81) ~2.42
Step-by-step explanation:
Given
-45 < 5(p-2)
Dividing both sides by 5
9 < p - 2
Adding two on both sides
9 + 2 < p - 2 + 2
11 < p
or
p > 11
