Question on chapter 1 exercise 2

[alexandrekow]

I tried to do the exercises in chapter 1 but I am not sure of my solution.

1. What is the expected percentage increase in text-message rates? hint: compute the mean of lambda_1_samples/lambda_2_samples. Note that this quantity is very different from lambda_1_samples.mean()/lambda_2_samples.mean().

When I do

print (lambda_1_samples/lambda_2_samples).mean(), lambda_1_samples.mean()/(lambda_2_samples.mean()

I find:

0.783421896592 0.782213782031

and they don't look very different to me.

Am I doing something wrong?
Is there a page with the solutions?

Hehe I guess this is just a bad problem, and it turns out they are almost they same! I'll confirm later

Ok, thanks :)
