1.) Tonight, please complete the following in your textbook--CHECK the CONDITIONS and DO THE MATH! This will force you to do some vocab studying (conditions) and review the math for our classwork tomorrow!
Page 429:
- 15
- This question asks for the probability that the newspaper's sample will predict defeat--remember, for a vote (on the budget) to be defeated, the "percent of the sample" would have to be less than 50%!
- Conditions then math!
- 41ac
- Only one of these questions (a or c) requires you to use a sampling distribution! It's your job to decide which!
- For the part that IS based on the sampling distribution for means check the conditions and do the math!
2.) Chapter 18 Vocab Quiz Tomorrow! Here's the vocab list:
- 10% Condition (know what it is why we check it)
- Randomization Condition (know what it is why we check it)
- Success/Failure Condition (know what it is why we check it)
- Large Enough Sample Condition (know what it is why we check it)
- 3 conditions for a sampling distribution for proportions
- 3 conditions for a sampling distribution for means
- Sampling Variability (aka sampling error)
- Sampling Distribution
- Sampling distribution for proportions = categorical data
- Sampling distribution for means = quantitative data
- Central Limit Theorem
- Standard Error
- Know how increasing/decreasing sample size affects standard error
- Identify which question requires the use of a sampling distribution
3.) Get me my money!
- Remember your AP Forms and $ are due March 1st!
