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.
Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
Answer: See explanation
Step-by-step explanation:
You didn't state the sentences but let me help out based on the information given.
Number of new motion toys = 12
Number of batteries used by each toy = 3
Since N represents the total number of batteries he need, the value of N will be:
= Number of toys × Number of batteries used by each toy
= 12 × 3
= 36
That means N equals 36.
Answer:
(7x9)x10 the power of 3 is 63,000
