If the p-value is greater than the level of significance (alpha), then you fail to reject the null hypothesis (H0). This is like saying we don't have enough evidence to reject the null hypothesis so we effectively accept it for now.
Answer is choice B) fail to reject the null hypothesis

Answer:
- 615.8 square feet
- 9 truckloads
Step-by-step explanation:
The area of the circular ring is given by the formula ...
A = πr²
where r is the radius, or half the diameter.
A = π(14 ft)² = 196π ft² ≈ 615.752 ft²
The area of the training area is about 615.8 square feet.
__
The number of truckloads of dirt required for coverage will be ...
(615.8 ft²)/(75 ft²/truckload) ≈ 8.21 truckloads
Since the dirt comes only in whole truckloads, Hilary needs 9 truckloads.

Step-by-step explanation:
79.99*1.06= 84.7894
For this one the answer is Not equal
For a 99% confidence interval for
μ based on a simple random sample.
Part (a):
Is it correct to say that
the probability that μ is in the specified interval is 99%?
Explain.
No. The probability that μ falls inside the interval is 0 or 1.
Rather we say that we are 99% confident that μ will fall inside the interval.
Part B:
Is it correct to say that in the long run, if you computed many,
many confidence intervals using the prescribed method, about 99% of
such intervals would contain μ?
Yes. 99% of intervals constructed using this method will capture
the population mean μ.
