Answer:
accept Null hypothesis at ∝ = 0.05
Step-by-step explanation:
To test the hypothesis that: X is b( 3, 0.3 ) ( Null hypothesis )
Let X = number of heads out of three spins
In three spins there were 4 outcomes
Ao = 0 , A1 = 1 , A2 = 2 , A2 = 3 { 0,1,2,3 } outcomes in three spins
next: lets determine the probability of each result
attached below is the detailed solution
H0 : pi = pio
where i = 0,1,2,3
Given:
Length of a carton = feet
Width of a carton = feet
Height of a carton = feet
To find:
The volume of the carton.
Solution:
We know that, volume of the carton is
Putting the values, we get
Taking LCM, we get
So, the volume is cubic feet.
Therefore, the correct option is A.
