Answer:
The test statistic is t = 3.36.
Step-by-step explanation:
You're testing the claim that the mean difference is greater than 0.7.
At the null hypothesis, we test if it is 0.7 or less, that is:
At the alternate hypothesis, we test if it is greater than 0.7, that is:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
0.7 is tested at the null hypothesis:
This means that
Survey of 35 people. From the sample, the mean difference was 0.95, with a standard deviation of 0.44.
This means that
Calculate the test statistic
The test statistic is t = 3.36.
Answer:
Option A -
Step-by-step explanation:
Given: The volume of a cylinder =
Let us substitute the volume of cylinder in the formula.
The formula for volume of a cone is (1)
The formula for volume of a cylinder is (2)
Substituting in equation (2), we get,
Given that the cone has the same radius and height of that of the cylinder, let us substitute in equation (1)
Thus, the volume of a cone with the same radius and height of a cylinder is .
