Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H_0: p1 - p2=0
H_a: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575

Answer:
The slope is -5/1 and the y-intercept is 7.
Step-by-step explanation:
1 ) p ( 2 )= 6 · 2³ = 6 · 8 = 48
Answer: B ) p ( x ) = 6 x³
2 ) 27 x³ + y^6 = ( 3 x + y² ) ( 9 x² - 3 x y² + y^4 )
Answer: D )
3 ) For even function: f ( -x ) = f ( x )
f ( x ) = x²
f ( - x ) = ( - x )² = x²
Answer: A ) f ( x ) = x²
