3(x+1) + 4(x) = 2x(x+1)
3x + 3 + 4x = 2x^2 + 2x
2x^2 - 5x - 3 = 0
if we factorise the quadratic equation
(2x + 1)(x - 3)=0
2x + 1 = 0 or x - 3 = 0
so x = -1/2 or x = 3

Answer:

So the value of the test statistic is -0.85.

Step-by-step explanation:

We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.
