4. What percent of values is between the first and third quartiles?
5. Find the interquartile range.

Answer:
IQR = 2.5
Step-by-step explanation:
Question 5:
IQR=Q1-Q3
IQR=4.75-2.25 = 2.5
Question 4:
Q1=2.5 and Q3=4.75 between those two is the median so, it may be 3.0 or 3% just not positive on question 4.
Can anyone else help on question 4?
