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
Answer: The median is 30.
1.) Line up each number in numerical order based on the data set.
- 27, 28, 28, 29, 29, 29, 30, 30, 30, 31, 31, 31, 33, 34.
2.) Cross out the numbers from inside out. (Find the middle number.)
- Because the data set has an even amount of numbers, you are left with 2 middle numbers. (30 & 30)
- In this case, you add the numbers together (30 + 30) and divide them by 2. (60/2)
- You end with the result of 30, therefore your answer (the median) is 30.
