1. Roll the die 40 times and record the rolled values in the table below. These represent 40 observations of X. 2. Calculate the sample mean of your 40 rolls using Excel. This number represents a single observation of the random variable X (which, again, is a random variable representing the sample mean of 40 rolls of a die). Record the value for the sample mean in the space below: Sample Mean Observation (= first observation of X): 4. Do...
