Firstly, arrange the data.
19 23 26 28 28 30 31 35 38 40 43 46
a) 5 number summary
-min value = 19
- Q1= (26+28/2) = 27
- Q2/ Median = (30+31/2)= 30.5
- Q3= (38+40/2)= 39
- Max value- 46
b) range= max value-min value
∴46-19= 21
c)interquartile range = Q3-Q1
= 39-27
=12
Question:
Katy makes 48 cookies an hour. If she has 24 already, how long would it take her to make 120?
Answer:

1 represents the units
2 represents the tens
3 represents the hundreds
4 represents the thousands
5 represents the ten thousands
6 represents the hundred thousands</span>
