Use the substitution method to solve the system of equations. 2x - y = 10 3x - 2y = 8

Lady bird [3.3K]

2x-y=10
3x-2y=8

-y= -2x +10 multiply by(-1)
y=2x-10

3x-2(2x-10)=8
3x-4x+20=8
-x=-12 multply by (-1)
x=12
24-y =10
-y=-14

Find the P- value for the hypothesis test with the standardized test statistic z. Decide whether to reject H 0 for the level of

kkurt [141]

Answer:

Option B) 0.1032; fail to reject $H_0$

Step-by-step explanation:

We are given the following information in the question:

We used two tailed z-test to perform the hypothesis.

$z_{\text{stat}} = -1.63$

Level of significance, α = 0.05

We have to calculate the p-value.

We calculate the p-value from the normal standard z-table.

p-value = 0.1032

Since,

p-value > Level of significance

We fail to reject the null hypothesis and accept it.

Option B) 0.1032; fail to reject null hypothesis
