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.
[tex]\text{Range of group A}=82-76=6[/tex]
[tex]\text{Range of group B}=81-76=5[/tex]
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.
