First, you want to divide both sides by 3 to isolate your variable. You get x^2 = 9. The square root of x^2 and 9 equals x = 3.

x = 3 is your answer.

1/2 (3/2 y + 1/3) = -1/2 (y- 5/2)

dem82 [27]

1/2 [ (3/2)y + 1/3] = -1/2 [y-5/2]

(3/2)y + 1/3 = -(1/2)y + 3

(3/2 + 1/2)y = 3 - 1/3

2y = 8/3

y = 4/3

y = 1.33

Answer:

$z_{stat} = -1.50$

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 108

Sample mean, $\bar{x}$ = 107

Sample size, n = 110

Alpha, α = 0.02

Population standard deviation, σ = 7

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{107 - 108}{\frac{7}{\sqrt{110}} } = -1.50$

The test statistic is -1.50
