$($Adapted from Camm Case $2\mathrm{.}1$ Heavenly Chocolates$)$ Review the data on the worksheet named "Heavenly Chocolates" where there are four types of variables: Txn Num $($Customer$),$ Day, Browser, Time, Pages Viewed, and Amount Spent. With this data in mind, please answer the following questions. NOTE: Txn Num is simply a transaction number. This is like a "receipt number" simply to uniquely identify each transaction. The original problem in the text named this column "Customer" and we renamed this to $"$Txn Num" to try and reduce ambiguity or uncertainty. This is NOT a unique customer ID$.$
