Let's solve the questions one by one based on the two-way table provided in the image:

### Table Recap:
|                    | Uses Spreadsheet | No Spreadsheet Use |
|--------------------|------------------|--------------------|
| **Female**          | 0.34             | 0.25               |
| **Male**            | 0.26             | 0.15               |

### Question A: What proportion of workers use a spreadsheet?

To find the total proportion of workers using a spreadsheet, we sum the proportions of females and males who use spreadsheets:
\[
\text{Total proportion using spreadsheets} = 0.34 + 0.26 = 0.60
\]

So, **0.60** or **60%** of workers use a spreadsheet.

---

### Question B: What proportion of male workers use a spreadsheet?

To answer this, we already know the proportion of male workers who use spreadsheets is given in the table:
\[
\text{Proportion of male workers using a spreadsheet} = 0.26
\]

So, **0.26** or **26%** of male workers use a spreadsheet.

---

### Question C: What proportion of spreadsheet users are female?

We need to calculate the conditional probability that a spreadsheet user is female. This can be calculated by dividing the proportion of female spreadsheet users by the total proportion of all spreadsheet users (which we found in question A).

\[
\text{Proportion of spreadsheet users that are female} = \frac{0.34}{0.60} = 0.5667
\]

Thus, approximately **0.567** or **56.67%** of spreadsheet users are female.

Would you like any further details or explanations? Here are some related questions you might consider:

1. What proportion of workers do not use spreadsheets?
2. What proportion of females do not use spreadsheets?
3. What proportion of males do not use spreadsheets?
4. How many females in total use computers at work, based on these proportions?
5. How can we find the proportion of workers who are male?

**Tip**: When dealing with proportions or probabilities, ensure that all the total proportions add up to 1 to avoid calculation mistakes!

Module 07 Two Way Tables: Problem 3 - What proportion of workers use a spreadsheet? What proportion of male workers use a spreadsheet? What proportion of spreadsheet users are female?

Explore joint and conditional probability concepts through the analysis of spreadsheet usage by gender. This problem involves calculating the total proportion of workers who use spreadsheets, the proportion of male workers using spreadsheets, and the percentage of spreadsheet users who are female.
