30.6

31.2

31.5

Answer 1

I don't see the actual length and frequency numbers in your message. Could you paste the table (lengths and corresponding frequencies) or upload the image?

If you want to compute it yourself, use this method:

1. Multiply each length (x) by its frequency (f) to get fx.
2. Sum all fx to get Σ(fx).
3. Sum all frequencies to get Σf.
4. Mean = Σ(fx) / Σf.

If you post the table I will compute the mean and pick the correct choice for you.
