0.03, 1/5, 3/10, 1/3, 5/8, 0.83
Answer:
43.96
Step-by-step explanation:
you do 6 divided by 2 to find the radius
then u find the volume
v= r^2h/3
v=3.14(3 to the power of 2)7/3
hope this helps
correct me if this is wrong
Answer: B) There is not convincing evidence because the interval contains 0.
==============================================================
Explanation:
The 98% confidence interval (-0.36, 0.22) means we are 98% confident that the difference of proportions p1-p2 is somewhere between those two endpoints of -0.36 and 0.22 Values in this interval are possible values of p1-p2.
Note how 0 is in this interval. So it's possible that p1 - p2 = 0. Because of this, we fail to reject the null hypothesis. The null in this case is that p1 - p2 = 0 which can be restated as p1 = p2. The null is the assumption that the two population proportions (p1 and p2) are the same.
The alternative hypothesis is that p1-p2 is not zero. If we got a confidence interval like (0.22, 0.55), this example doesn't have 0 in the interval, then that would mean we reject the null since its unlikely that p1-p2 is equal to zero.
----------------
In short,
- If the confidence interval contains 0, then you fail to reject the null
- If the confidence interval doesn't contain 0, then you reject the null.
In this case, we fail to reject the null and we don't have enough evidence to show that p1 = p2 is false. So for now, we assume it's true.
