TinkerPlots provides an excellent modeling environment to illustrate the Central Limit Theorem. Three activities were generated in Summer 2013 (online graduate course). Note that the randomNormal function was used to create the simulations.

Shower Times Find the probability that the mean time of a random sample of 35 Americans who shower is more than 14 minutes.
The steps for creating the model in TinkerPlots are shown in this activity. Oven Repair
If 42 ovens are repaired, find the probability that the mean of the repair bills will be greater than $57.

## Central Limit Theorem

TinkerPlots provides an excellent modeling environment to illustrate the Central Limit Theorem. Three activities were generated in Summer 2013 (online graduate course). Note that the randomNormal function was used to create the simulations.

Shower Times

Find the probability that the mean time of a random sample of 35 Americans who shower is more than 14 minutes.

The steps for creating the model in TinkerPlots are shown in this activity.

Oven Repair

If 42 ovens are repaired, find the probability that the mean of the repair bills will be greater than $57.

The steps for creating the model in TinkerPlots are shown in this activity.

SAT-ACT

Simulations were completed with SAT and ACT data to model the CLT.
