Answer:
1st option is correct.
Step by step explanation:
Let us see our given options one by one.
1. We can see that median of group A is 79 and median of group B is 79.5. Therefore, median of group A is less than group B and 1st statement is correct.
2. Let us find range of each group.
We can see that range of group A is greater than group B, therefore, 2nd statement is false.
3. The lower quartile of group A is 78 and lower quartile of group B is 77. We can see that 78 is greater than 77, therefore, 3rd statement is false.

Answer:
2nd debate was 3 hours long.
Step-by-step explanation:
We have been given that during the mayoral election,two debates were held between the candidates. The first debate lasted 1 2/3 hours. The second one was 1 4/5 times as long as the first one.
Let us find the estimate of time spent on 2nd debate.
1 2/3 hours would be approximately 2 hours. 1 4/5 times would be equal to 2 times.
Therefore, the estimated time is less 4 hours.
To find the time spent on 2nd debate, we will multiply 1 2/3 by 1 4/5.
First of all, we will convert mixed fractions into improper fractions as:
Now, we will multiply both fractions as:
Therefore, the 2nd debate was 3 hours long.
