The standard divination of a set of data is 9.5 the mean is 205 what is the margin of error

Step-by-step explanation:

Margin of error = critical value × standard deviation

We aren't given the critical value or any information to calculate it, so we need to make some assumptions.  Assuming the data set is large enough to be approximated as normal, and that the confidence level is 95%, then the critical value is 1.96.

ME = 1.96 × 9.5

ME = 18.62

You may choose to round 1.96 to 2, in which case the margin of error is:

ME = 2 × 9.5

ME = 19

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.
