Please help!!

18) If we use the min, max, median, Q₁, and Q, then we are using what we call the 5-number summary. Using these,
make a box and whisker plot for Jose's data right above his dot plot.
19) Now go back and make box and whisker plots for the other 5 people's data sets.
20) What percentage of the data is at or above Q₁?,
What percentage of the data is at or above Q₁?
What percentage is at or below Q₁?
What percentage is at or below Q₁?
21) If you subtract the Q₁ and Q, then you get what we call the inner quartile range. What does this IQR describe?
22) Go back and find the IQR for each person's data.
23) Do the box and whisker plots support what you put for answers to #9 using the spread of the data?
24) Explain why both the median and mean are called "measures of center".
