Answer:
The answer is -1.2
Step-by-step explanation:
Recalling the standard deviation formula,
we have : σ = sqrt[ P * ( 1 - P ) / n ]
Where sqrt = square root
n = Number of derivative
Therefore,:
if, H0: p is not 48% vs H1: p1 = 48%
standard deviation is:
σ = sqrt[ P * ( 1 - P ) / n ] = sqrt[ .48*.49/900 ] = .01666333+
z -score is (p-P)/σ
= (.51-.53)/.01666333
The answer therefore = -1.2
ICONCLUSION:
It can therefore be concluded that there is statistical evidence that the proportions are different. H0 accepted in the hypothesis.
The answer is 24 because the least common multiple of 6 and 8 is 24.
B. 6
Explanation: 8(6+4)= 80
38+ 7(6)= 80
3*-2=-6
-6*-2=12
The sequence is a number being multiplied by -2 over and over.
48, -96, 192, -384, 768, etc.
