observations

Answer 1

To find the total number of observations represented in Sven's dataset from the tally chart, we need to count the tallies for each category of flights taken by friends.

• For 0 flights: 4 tallies (4 friends)
• For 1 flight: 3 tallies (3 friends)
• For 2 flights: 0 tallies (0 friends)
• For 3 flights: 1 tally (1 friend)
• For 4 or more flights: 3 tallies (3 friends)

Now, we sum these up:

4 (0 flights) + 3 (1 flight) + 0 (2 flights) + 1 (3 flights) + 3 (4 or more flights) = 11

So, there are a total of 11 observations in Sven's dataset.
