The greatest number that will be rounded down to 2,500 would be 2549.
2550 would be rounded to 2600
So the least is 2450.
Greatest : 2,549.
Least : 2,450
Hope this helps!-Aparri

Just use Pythagorean theorem.
Trust me lol
Answer:
sample standard deviation is $50
Step-by-step explanation:
Given a population standard deviation of $500 and a random sample of size, n=100.
-The sample standard deviation is calculated using the formula:
Where:
- is the sample standard deviation.
- is the sample size.
- is the population standard deviation
Therefore:
Hence, the sampling distribution has a mean of $1,500 and a standard deviation of $50
