Part 2: Basic Inferential Data Analysis Instructions (COursera Johns Hopkins University Data Sience Specialization) Load the ToothGrowth data and perform some basic exploratory data analyses Provide a basic summary of the data. Use confidence intervals and/or hypothesis tests to compare tooth growth by supp and dose. (Only use the techniques from class, even if there's other approaches worth considering) State your conclusions and the assumptions needed for your conclusions.

Part 1: Simulation Exercise Instructions llustrate via simulation and associated explanatory text the properties of the distribution of the mean of 40 exponentials. You should 1- Show the sample mean and compare it to the theoretical mean of the distribution. 2- Show how variable the sample is (via variance) and compare it to the theoretical variance of the distribution. 3- Show that the distribution is approximately normal.
