Answer:
Do no reject null hypothesis.
Conclusion:
there is no sufficient statistical evidence at 0.025 level of significance to support the claim.
Step-by-step explanation:
Given that;
mean x" = 5.4
standard deviation σ = 0.7
n = 6
Null hypothesis H₀ : μ = 5.0
Alternative hypothesis H₁ : μ > 5.0
∝ = 0.025
now,
t = ( 5.4 - 5.0) / ( 0.7/√6) = 0.4 / 0.2857 = 1.4
degree of freedom df = n-1 = 6 - 1 = 5
T critical = 2.571
Therefore; t < T critical,
Do no reject null hypothesis.
Conclusion:
there is no sufficient statistical evidence at 0.025 level of significance to support the claim.
Answer:
The APY of the saving account is 4.0474%
Step-by-step explanation:
We know the formula for APY which is given by
here, r= interset rate = 3.9742% = 0.039742
n = compounding cycles = 12
On plugging these values in the above formula, we get
On simplifying this we get
APY =0.04047395=4.0474%
Answer:
16 tricycles
12 bicycles
Step-by-step explanation:
If all were bicycles, there would be 28·2 = 56 wheels. Each additional wheel indicates the presence of a tricycle instead of a bicycle.
There are 72 -56 = 16 tricycles. The remaining 28-16 = 12 are bicycles.
Point P is certainly the outlier because the other points are all consistent with the string of data while Point P is alone with no other data around it.
