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.

Answer:
M = - 19/2 or in decimal form - 9.5
Step-by-step explanation:
1. Subtract
4 from both sides.
M/3 = 5/6 - 4
2. Simplify
5/6
− 4 to −19/6
3. Multiply both sides by
3.
M = - 19/6 x 3
4. Simplify 19/6 × 3 to 57/6
M = -57/6
5. Simplify 57/6 to 19/2
M = - 19/2
