Answer:
Yes
Step-by-step explanation:
Yes
We have the sample size, sample mean and the sample standard deviation. Since the population standard deviation is not know, we will use t-distribution to find the confidence interval.
The critical t value for 95% confidence interval and 63 degrees of freedom is 1.998.
The 95% confidence for the population mean will be:

Thus, the 95% confidence interval for the population mean will be (115,123)
So, option A is the correct answer
Answer:

Step-by-step explanation:
Cylinder volume formula is 




Yes because fraction wise the denominator that is the smallest is greater. At least that is what I learned
Bigger to smaller I think...
take the smaller length divide by the larger length
1.45/5.8 = 0.25
