Answer:
Option A
Step-by-step explanation:
The unit volume explains it all.
Volumes are measured in units of length cubed. This also is the volume occupied by unit cubes.
By unit cubes, I meant, view the photo above
The volume of an object's says, how many of these cubes will fill that object.
It may not necessarily by a whole number.
So, the answer is Option A
Answer:
{13.7756,18.2244}
Step-by-step explanation:
Given the sample size, the margin of error can be calculated with the formula where Z is the critical value for the desired confidence level, σ is the population standard deviation, and n is the sample size. Therefore, our margin of error for a 90% confidence level is:
The formula for a confidence interval is where x-bar is the sample mean. Therefore, the 90% confidence interval for the mean amount of sushi pieces a person can eat is:
Therefore, we are 90% confident that the true mean amount of sushi pieces a person can eat is contained within the interval {13.7756,18.2244}
