Join forces with the other group who answered the same question as you on 6.10-6.11 to compare answers and finalize your confidence interval and hypothesis test.
In your original pair, prepare one person to describe the confidence interval and the other to describe the hypothesis test.
Even questions make two groups odd questions make two groups. Have the confidence interval people explain their process and results then the hypothesis test people go next. This is your chance to solidify your understanding and make any corrections to your work!
Bonus: Can you calculate the probability that the conclusion that you got was wrong?
This will count as a summative grade. 5 points for each side.
