Answer:
Step-by-step explanation:
To Test :-
H0 :- P = 0.12
H1 :- P ≠ 0.12
P = X / n = 156/800 = 0.195
Test Statistic :-
Z = ( P - P0 ) / ( √((P0 * q0)/n)
Z = ( 0.195 - 0.12 ) / ( √(( 0.12 * 0.88) /800))
Z = 6.5279
Test Criteria :-
Reject null hypothesis if Z > Z(α/2)
Z(α/2) = Z(0.05/2) = 1.96
Z > Z(α/2) = 6.5279 > 1.96, hence we reject the null hypothesis
Conclusion :- We Reject H0
There is sufficient evidence to support the claim that there is a difference.
Answer:
Area of rectangle = Base times height
Answer:
D
Step-by-step explanation:
D is not a function because x's repeat. Each x value should have its own unique y value. The graph also fails the vertical line test, meaning that if you were to draw a vertical line anywhere on the graph it would intersect with more than one point.
-4 1/2 divided by 3-4 = 5.5
