Question

The purpose and intent of this is to help you better understand the sampling distribution of
the mean.
The class sampling exercise
In class we conducted a sampling exercise.
The population consisted of 25 elements.
The possible values for the elements in the population ranged from 1 to 9 and were distributed as
follows:
Value Frequency Proportion Percentage
1 1 0.04 4%
2 2 0.08 8%
3 3 0.12 12%
4 4 0.16 16%
5    5 0.2 20%
6 4 0.16 16%
7    3 0.12 12%
8 2 0.08 8%
9    1 0.04 4%
As in the class exercise, 10 elements are drawn replacing each element before the next is drawn.
This was done 1000 times.

The data set is given in a separate spreadsheet and consists of the numbers drawn for these 1000 draws
in the order in which these were drawn. Each line can be considered a
With all calculations, include the formula that you used.

Let’s start with a few questions about the population. The population is the complete set of
elements from which the samples are drawn.

5. What is the mean of the population?
6. What is the median of the population?
7. What is the standard deviation of the population?

Using Excel, compute the mean and standard deviation for each of the samples. Each sample will
have a mean and a standard deviation.
14. What, theoretically, would be the highest sample mean that could ever be observed?

let me know if the screenshot provided is enough to solve the questions or if the 1000 draws would be necessary.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
