Point Estimates and ci Proportions

1st Homework Assignment:
  1. Unit 6 Test corrections and Test Re-Take (Due by Friday the 24th)
  2. We will be working from our Against All Odds Packet as well as 5 Steps to a 5 book from now on.  Please note, there are quite a few videos, some of which are used by Universities and in AP Research.  They really make confidence intervals make sense, so if you miss class, watch the videos to the right!  Trust me :)
  3. Go to Class Google Spreadsheet.  Complete for your sample set the 90% and 99% confidence interval.
  4. Classroom Packet Exercise Problems #1 and 2.
  5. Keep working on Frappy Packet #2
2nd Homework Assignment:
  1. Go to Class Google Spreadsheet.  Complete the t-test distribution for the 95% confidence interval only.  If you missed class on Friday, please review the video Against All Odds: One Sample Mean to the right.
    To complete the assignment, you will have to
    1. Take your given 6 sample runs
    2. Find the mean (which we already did) for each sample
    3. Find the standard deviation by hand using the formula from Unit I for each sample.
    4. Use the t-distribution table in the back of the 5 Steps to a 5 Book to find the t-score
    5. Combine the mean, the t-score, the sample standard deviation, and sample size into the t-confidence interval.
  2. Unit 6 Test corrections and Test Re-Take (Due by Friday the 24th)
  3. Classroom Packet Exercise Problems #3 and 4.
  4. Keep working on Frappy Packet #2 (Due Friday)
