In an equilateral triangle (all sides and anges are equal)
angles are 60 degrees each
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
