Michigan doesn't have very exact stats for this. Take a look at the map in the link below, which states somewhere between 20 and 99 people work in Cali from class of 2009 to 2011 combined.

As per this next link, c/o 2009-2011 combined apparently have 84 graduates working either in the Bay Area or LA.

As a proportion of their class, 84 out of (379 + 374+ 412) = roughly 7.21% of the classes of 2009-2011 work in CA
This may be leaving out grads outside of those two areas, but I'm guessing it's a negligible amount on the basis of the first link that states that more than 20 but less than 100 work in Cali.
Duke doesn't have c/o 2011 stats yet. For c/o 2010, they claim a little over 16% worked in the "West", and, specifically, 10.9% ended up in California. For c/o 2009, that percentage is 11.5%. For 2008, 10.3%.

Specifically, 22, 24, and 21 people from 2010, 2009, and 2008 respectively ended up in Cali, a total of 67.
With respective class sizes of 213,219, and 207, (639 total), the overall percentage from 08-10 in Cali is 10.49%

I wouldn't put too much stock in the pure percentages. What you should be looking at is what types of firms show up to each places EPI/OCI. How many of the big Cali firms show up? How many firms with big Cali branches show up? Those are what really matter.
