Answer:
Step-by-step explanation:
Given that :
the null and the alternative hypothesis are computed as :
This is a two tailed test
This is because of the ≠ sign in the alternative hypothesis which signifies that the rejection region in the alternative hypothesis are at the both sides of the hypothesized mean difference .
Decision Rule: at the level of significance ∝ = 0 . 10
The decision rule is to reject the null hypothesis if z < - 1 . 64 and z > 1 . 64

Hi there!
v = √2gh
Plug in the given velocity and acceleration due to gravity:
48 = √2(32)h
Square both sides:
2304 = 2(32)h
Simplify:
2304 = 64h
Divide both sides by 64:
h = 36 feet.
Answer:
y = -1/2x-8
Step-by-step explanation:
If the lines are parallel, they have the same slope.
y = -1/2x +3 is in the form y=mx+b where m is the slope and b is the y intercept
-1/2 is the slope so the new line will have a slope of -1/2
(0,-8) is the y intercept since x=0
We can write the equation since we know the slope (-1/2) and the y intercept (-8)
y = -1/2x-8
