Answer:
549.8 inches³
Step-by-step explanation:
Volume of Cylinder = height × base, where base = r².
The radius (r) is given, 5 inches, and so is the height, 7 inches.
We simply substitute these values into the equation.
V(volume) = 7 × × 5²
= 175
= 549.77871437821...
when we round that to the nearest tenth,
≈ 549. 8
Answer:
We are given:
Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.
Since the alternative hypothesis has less than sign, therefore the given hypothesis is left-tailed
What parameter is being tested?
The parameter used is , which denotes the population mean.
Please note:
The type is test determined based on the alternative hypothesis.
If the alternative hypothesis has sign, it means the hypothesis test is two-tailed
If the alternative hypothesis has sign, it means the hypothesis test is right-tailed
If the alternative hypothesis has sign, it means the hypothesis test is left-tailed
