Replace all uses of inference() with step-by-step R code #2

Open beanumber opened 10 years ago

beanumber commented 10 years ago

The inference() function is undocumented and creates an umbrella for many different types of operations. It may be preferable to have students reinforce their learning by doing these operations step-by-step.

This pops up in Lab 5 and Lab 6.

This is done for Lab 6. Naomi, please use this as a guide for Lab 5.

Done, but it might be worth adding some more explanation on how the p-value is computed (why we have to -1 * absolute value, why we have to multiply by 2) and on how the standard error is computed.

Also, we might want to add an exercise asking them to interpret the results of the hypothesis test. The original lab didn't have this but it seems like a good idea.
