For question 6, choose one of the questions below to answer.    I will not grade both if you answer both; if you answer both options, I will grade the first one have typed out.  Option 1:  Give an example of a right-skewed variable and explain what makes it right-skewed.  Note there are no restrictions on the variable you choose, as long as it is right-skewed. Option 2:  Consider the integers  13, 14, 15, 16, 17.  Using only these numbers, create a dataset with n = 4 values,
