The mean is the average. You calculate it by adding all the numbers up in the data set and divide by how many numbers there are in the data set.

So:

\sf Mean=\dfrac{70+68+72+66+68+69+66+71+74+66}{10}\rightarrow\dfrac{690}{10}\rightarrow\boxed{\sf 69}

Sara can type 90 words in 4 minutes.About how many words would you expect her to type in 10 minutes?

You can expect her to type 225 words in 10 minutes.
