Quiz Tomorrow!

Hey! Check out this article (Statistician job profile) from U.S. News for a quick glimpse of how awesome the career of "Statistician" is!

Tomorrow we will start with a short (10 minute) quiz: here's what's on it!

• Identify the sample (including sample size)
• Define the population of interest
• Define the population parameter of interest
• Identify p-hat, q-hat, and x
• Check the conditions for a one-proportion z-interval
• Random sample?
• sample < 10% of population
• (n)(p-hat)>10 and (n)(q-hat)>10
• State "A one proportion z interval is appropriate."

After our quiz we'll get back to the context regarding the % of people who are married or living with their partner, and we'll figure out the formula for a confidence interval! See you there!

So, your only homework tonight is to be ready for the quiz tomorrow! (look over #'s 1,2 on today's stamp/classwork example!)
