Answer:
Step-by-step explanation:
To break down the volume even more, the base of a cylinder is pi(r)^2
Instead of V=Bh use V=pi(r)^2h (it's broken down more so it's easier to understand)
So just plug in the values to make B:
B=pi(r)^2
B= pi(8.3)^2
Answer:
Step-by-step explanation:
12z - 3 > 27z - 15
-15z - 3 > -15
-15z > -12
z < 12/15= 4/5
Answer:
The point estimate for the proportion is p = 0.4725
The 95% confidence interval for the proportion of non-fatal accidents that involved the use of a cell phone is (0.4236, 0.5214).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
Point estimate
95% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the proportion of non-fatal accidents that involved the use of a cell phone is (0.4236, 0.5214).
