Answer:
a)
H₀ : µd = 0
H₁ : µd < 0
b)
The test statistic is
tₙ₋₁ = α / s√n
c)
at 0.10 level of significance,
tₙ₋₁ , ₐ
t₃₀₋₁ , ₀.₁₀ = t₂₉, ₀.₁₀ = 1.311
d)
given that T(critical) = 1.62
∴ T(critical) = 1.62 > t₂₉, ₀.₁₀ = 1.311
at 10% level of significance,
REJECT H₀
Since 1.62 > 1.311, we can reject the null hypothesis.
Answer:
D
Step-by-step explanation:
intercept is -4 and slope is rise over run which is 3/1 = 3
put into slope intercept form to achieve answer D
The given equation is
The slope of the given line is 6.
It is important to know that parallel lines have the same slopes, so the slope of the new line is 6.
Now, we use the point-slope formula to find the new line
Let's replace the point (-4,7) and the slope 6.
<h2>Hence, the equation of the new parallel line in slope-intercept is</h2>
<h2>In point-slope form is</h2>
Answer:
And the best option would be:
Step-by-step explanation:
We assume that the distribution for the random variable is:
For this case we want to calculate the following probability:
And we can use the normal standard distribution or excel and we got:
