It is given in the question that the solid is a cone with height of 16 units and radius of 7 units .
The formula of volume of cone is
To find the volume, we substitute the given values of r and h and use 3.14 for pi. That is
And that's the required volume of the cone .
Answer:
The value of the test statistic is
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis,
is the standard deviation(square roof of the variance) and n is the size of the sample.
In this problem, we have that:
So
The value of the test statistic is
