helpful thanks

Hey I have a biostat exam on Monday. Wish me luck.

At 1:04 the NPV calculation should read NPV = 0.996 rather than 0.10. Apologies for the typo.

Do not forget to weight the data

nice presentation... looks great and is easy to follow.

Your lecture is very fine and essential for us

Thanks, helpful......... especially adding in weighted cases :-)

Great module!

You're right! Thanks for spotting that typo; I appreciate it.

example 5 is wrong answer: it is -8/2.5 equal -3.2 which is .0007
