well none of the answer choices match up with all these statements ...
C. it only matches up with the y-intercept given
D. it matches with the y-intercept, and the x- intercept is not quite on the 1
*but i would say C is the closest, because it has an x-intercept of -1 and the maximum point is at (1,4) ... which are the same with the given statements except that they have opposite signs, but yeah i have no clue*
3 point slope
1 slope intercept
2 standard
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, 2)
m = 
=
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.
