For continuous uniform distribution over interval (-4,8) its variance is equal to ?

Answer 1

Answer:

Step-by-step explanation:

xADsCs

Answer 2

Concept: The uniform distribution is employed to explain a state of affairs wherever all attainable outcomes of a random experiment area unit equally possible to occur. you'll use the variance and variance to live the "spread" among the attainable values of the likelihood distribution of a chance variable.

Given: Interval (-4,8).

Find: Calculate variance.

Solution: σ2=$\frac{(b-a)^{2}}{12}$

b=8

a=-4

σ2=$\frac{(8-(-4))^{2} }{12}$

σ2=$\frac{12X12}{12}$

σ2=12

Final answer: variance of Interval (-4,8) is 12.
