Exercise

Even more on sampling

Note that we're able to use a single for loop to build two distributions by adding additional lines inside the curly braces.

Don't worry about the fact that samp is used for the name of two different objects. In the second command of the for loop, the mean of samp is saved to the relevant place in the vector sample_means10.

With the mean saved, we're now free to overwrite the object samp with a new sample, this time of size 50

In general, anytime you create an object using a name that is already in use, the old object will get replaced with the new one, i.e. R will write over the existing object with the new one, which is something you want to be careful about if you don't intend to do so.
