Ierofanga [76]

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.

Find the roots of the equation: 2(x−3)^2=3·(2x−11)
bekas [8.4K]

Answer:

5 and 4

Step-by-step explanation:

2(x-3)^2➡ 2×(x^2-6x+9) ➡ 2x^2-12x+18 = 6x-22

transfer and add like terms

2x^2-12x-6x=-22-18

2x^2-18x = -40

2x^2 - 18x + 40 = 0

(2x-8)(x-5)

x = 5 or, x = 8/2 ➡ 4
