Answer 1

1). 68 observations

1.2) 8 variables

1.3) Quantitative Variables: Type, Time, Date, DayCode, Hour, and Amount

1.4) Qualitative Variables: Location, Weekday

Question 1) Let's examine that table to find out the number of collected observations. Counting each row, we have 68 observations. Each one informing the type, time, date, day code, weekday, Location, Hour, and Amount

1.2) We have then 8 variables namely (type, time, date, day code, weekday, Location, Hour, and Amount)

1.3) The Quantitative Variables are the ones whose entries are numerical, so examining then we can state that:

Type, Time, Date, DayCode, Hour, and Amount each and every one of them receives a numerical entry.

1.4) Qualitative or Categoricals variables are the ones whose entry is not a numerical one. So we can enlist the following ones as Qualitative:

Location

Weekday

Hence the answers are:

1). 68 observations

1.2) 8 variables

1.3) Quantitative Variables: Type, Time, Date, DayCode, Hour, and Amount

1.4) Qualitative Variables: Location, Weekday
