- If you lost yours you can find the questions below
- For #2 I would just enter x and n into the calculator, then enter each confidence level (obviously it's not A) and see which resulting interval comes closest to (60%, 69%)
- It's C, D, or E....
2.) Be sure to sign up for a time slot for our MANDATORY AP Saturday Sessions (April 1st and April 22nd)!
- The times are 9-10:30, 10:30 - 12, or 12-1:30
- You should sign up for one time slot on each date
- Spots are "first come first serve," and once a time slot is filled you cannot choose that time
- Pay attention to any other sessions!
- Sign up sheet is on the bulletin board in our classroom!
- We will be learning new stuff on these days! If you miss it'll be like missing 2 days of class! So don't do that!
Tomorrow in class it's on to chapter 22--2 proportion tests and intervals! See you there!
Oh...and here's the homework (take home test MC) in case you lost yours or were out:
Want some extra credit?
- Finally, if you want some extra credit, try out these True/False questions below
- Write the statement on a separate piece of paper (for me to collect) -- you MUST write the statement to receive any extra credit!
- Determine if the statement is true or false
- If the statement is false, explain why OR change the statement to make it correct!

1. A sample of 100 fuses from a very large shipment is found to have 10 that are defective. The 95% confidence interval would indicate that, for this shipment, the proportion of defective fuses is between 0 and 0.28.2. A point estimate consists of a single sample statistic that is used to estimate the true population parameter.3. A population parameter is used to estimate a confidence interval.4. Holding the sample size fixed, increasing the level of confidence in a confidence interval will lead to a wider confidence interval.5. The width of a confidence interval equals twice the margin of error.
