Answer:

The correct answers are:

-Less than 78

-More than 102

-Between 78 and 90

-Between 90 and 102

Step-by-step explanation:

Quartiles show where 25% of the population lies. Since the bottom quartile is 78, we know 25% would be under. Since 102 is the upper quartile, 25% would be above.

We can also create further quartiles between the median and those quartiles.
