Open the spreadsheet linked in today's assignment and run the experiment
We are going to pop a bag of popcorn. How many seconds do you think it will take before we hear the first pop?
How many seconds do you think it will take before the popcorn starts popping rapidly?
At what time will we reach the spot when the most popcorn is being popped?
Once you've filled in the spreadsheet scroll down and screenshot the graph that is below the numbers.
Paste the screenshot below.
What is the shape of your graph?
Using the spreadsheet, what was the average (mean) popping time?
Compare your graph in #7 to the curve in #11. How are they similar?
Compare your graph in #7 to the curve in #11. How are they different?
How many seconds do you think it will take before the popcorn starts slowing down?
At what time will the last popcorn pop?
Using the spreadsheet, what was the standard deviation (SD)?
Go to the following site and enter your mean and Standard Deviation from above then hit enter to create a normal curve for your data.
Screenshot the result and post it below.
Using the website on #11, what percentage kernels does the model predict popped between intervals -1 and 1?
To find this find the values on the curve that correspond with the location of -1 and 1 and enter them as I did below.
Using the website on #11, what percentage kernels does the model predict popped between intervals -2 and 2?
Using the website on #11, what percentage kernels does the model predict popped between intervals -3 and 3?
