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:
32'cube
Step-by-step explanation:
Just i have no paper and pen so i just calculated it in my mind so its not practically an accurate answer
It has no real solutions. To be precise, no real zeros (or roots).
The zeros (here called "solutions", I guess) are the points where the function intersects the x-axis: at those points the value of the function is zero. So they are solutions to the equation f(x)=0.
This function does not intersect the x-axis. Hence, no solutions.
A.
1 meter = 3.28 feet
Height = 199 / 3.28
Height = 60.6707 m
To the nearest hundredth = 60.67 m
B.
1 Kilometer = 1000 meter
1 meter = 3.28084 feet
1 kilometer = 3280.84 feet
Length = 26,372 / 3280.84
Length = 8.0382 km
To the nearest hundredth = 8.04 km<span />
