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: 7
Step-by-step explanation: 5 + 1 + 1 = 7 .
All you have to do is add the like terms.
(They are all like terms, so just add everything)
4c + 2c + c
6c + c
= 7c
Now we know that
7c = 266
We need to isolate c in 7c, to do that we will eliminate 7.
Eliminate it by dividing 7.
7c ÷ 7 =
[property of equality - also divide 7 on the other side since you are making changes to this side]
7c ÷ 7 = 266 ÷ 7
c = 38 [final answer]
