Math Problem Statement
Fill up the table for me with the solution and answers
Solution
import pandas as pd
Prepare the table columns
data = { 'X': X, 'P(X)': P_X, 'X * P(X)': [x * p for x, p in zip(X, P_X)], '(X - μ)': [x - mean for x in X], '(X - μ)^2 * P(X)': [(x - mean) ** 2 * p for x, p in zip(X, P_X)] }
Create the DataFrame
df = pd.DataFrame(data) dfHere is the filled table with the calculated values:
X | P(X) | X * P(X) | (X - μ) | (X - μ)² * P(X) |
---|---|---|---|---|
0 | 0.07 | 0.00 | -2.4 | 0.4032 |
1 | 0.18 | 0.18 | -1.4 | 0.3528 |
2 | 0.38 | 0.76 | -0.4 | 0.0608 |
3 | 0.12 | 0.36 | 0.6 | 0.0432 |
4 | 0.15 | 0.60 | 1.6 | 0.3840 |
5 | 0.10 | 0.50 | 2.6 | 0.6760 |
Total for (Mean ): 2.4
Total for (Variance ): 1.92
Do you have any other questions?
Here are 5 additional questions you might explore:
- How does altering the probabilities affect the distribution's mean and variance?
- Why is variance a good measure of dispersion in a dataset?
- Can two different distributions have the same mean but different variances?
- What happens to the standard deviation when all probabilities are the same?
- How can we visualize this probability distribution using a graph?
Tip: It's useful to create visual representations (such as histograms) to better understand how data is distributed.
