To calculate the total percentage of responses received across all business areas, we need to first determine the overall response rate. This involves:

1. Summing the total number of responses.
2. Summing the total number of employees surveyed.
3. Dividing the total number of responses by the total number of employees surveyed, and then multiplying by 100 to get the percentage.

Let's break it down step by step.

Step 1: Summing the total number of responses

$10 + 13 + 18 + 118 + 132 + 216 + 18 + 33 + 28 = 586$

Step 2: Summing the total number of employees surveyed

$20 + 30 + 64 + 380 + 365 + 590 + 52 + 51 + 67 = 1619$

Step 3: Calculating the total response rate

$\text{Total response rate} = \left( \frac{586}{1619} \right) \times 100$

$\text{Total response rate} \approx 36.19\%$

So, the overall percentage of responses received is approximately 36.19%.

Here are 5 follow-up questions to expand this discussion:

1. How can individual department response rates impact overall company morale?
2. What could be done to improve response rates across departments with lower participation?
3. How does the response rate relate to the validity or reliability of the survey data?
4. What strategies could the company employ to encourage more survey completions in the future?
5. What could be the consequences of low response rates in critical departments like Human Resources?

Tip: When calculating totals or averages, always double-check that all components (like responses and surveyed) are included in your calculations for accuracy.
