Answer:
T = 4.541
Step-by-step explanation:
We don't have the standard deviation for the population, so we use the t-distribution.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 4 - 1 = 3
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 3 degrees of freedom(y-axis) and a confidence level of . So we have T = 4.541
Answer:
Step-by-step explanation:
The formula for calculate the volume of a cylinder is:
r is the radius of the cylinder and h is the height of the cylinder.
Given the diameter of 3 inches, calculate the radius of the cylinder with:
(Where d is the diameter)
Knowing the height and the radius, you can calculate the volume of the entire can of tuna:
As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:
