Answer:
50 liters per minute.
Step-by-step explanation:
$920 would be the amount of interest in the first payment.
We convert the decimal to a monthly amount first. (5.5/100)/12 = 0.0046. We then multiply this by the amount of the loan, 200,000:
200000*0.0046 = 920.
$920 of the first month's payment would go towards interest.
To find the percentage of the payment, you would divide this amount by the amount of the first month's payment.
<h3>Answer: Statistic</h3>
===========================================================
Explanation:
The fact that we have the phrasing "randomly-selected" in there is a big clue that we are working with a sample, and not a population. If 40 people represented the population, then we wouldn't be randomly selecting anyone. Everyone would be surveyed. No random process needed. We don't need to worry about the order of those surveyed.
However, we are applying a random selection process to form this sample. A <u>statistic</u> is some value that measures a sample. For instance, xbar is the sample mean which is a sample statistic. The xbar value estimates mu, which is a greek letter. Mu is the population mean and a population parameter.
To remember the difference between the two terms parameter and statistic, one useful memory trick is to think of it like this:
- <u>Statistic</u> and sample both start with s
- Population and parameter both start with p
As the name "statistics" implies, it is the study of how to estimate a population based on a sample. After gathering the sample, we compute a statistic, which in turn estimates a parameter. So that explains why your math course and textbook has that label.
