The answer would be 14 cm.

The formula to find diameter is d=2r
D= diameter
R= radius
The 2 is there because you have half of the diameter so just times by 2 to get the diameter.

Describe in detail how you would construct a 95% confidence interval for a set of 30 data points whose mean is 20 and population

postnew [5]

Answer:

We have been given confidence interval 95%, mean 20 , data set 30 and standard deviation 3.

We will use the formula: $mean\pm \frac{\sigma}{\sqrt{n}}\cdot (z-score)$

Here, $mean=20,\sigma=3,n=30,z-score=1.96$

Z-score value at 95% confidence interval is 1.96

On substituting the values in the formula to plug the values:

$20\pm\frac{3}{\sqrt{30}}\cdot (1.96)$

Now, we have a formula for marginal error: $z\cdot \frac{\sigma}{\sqrt{n}}$

Marginal error means your answer will be within that percentage only.

Say you have 3% marginal means your value will be within 3% real population 95% of the time.
