Hello Jason, for the prediction interval calculation, could you explain what steps are taken using BEDMAS to get 8.6107? I am getting a different value. And also for the confidence interval, how did you solve it to get 2.6036?

I was wondering if you could make a video for the BEDMAS operations for part g). I was able to come to the correct solution on my own for part f) but I can’t seem to arrive at the same answer as you for the confidence interval. I wonder if there is something I am doing by mistake.

Would n=20 because of the 20 total samples?

No. The sample size is n=10 people. The sample size is based on the number of participants – not the total amount of data collected.

Hi Jason!

I was wondering if you could make a video for the BEDMAS operations for part g). I was able to come to the correct solution on my own for part f) but I can’t seem to arrive at the same answer as you for the confidence interval. I wonder if there is something I am doing by mistake.

Thank you in advance!

Good idea! I’ll get to work on a video covering order of operations and post it here.
