a =1, b=7
Step-by-step explanation:
hope this helps
first of all arrange this data from ascending to descending order.
11,15,15,15,16,17,18,19,20,22,23
use formula
N+1/4 (N means no of observations)
11+1/4
12/4
3 rd term
therefore Q1=15
0.6111111111111111111111111111
over and over non stop
77°F
C = 5/9 (F - 32)
25 = 5/9 (F - 32)
-----------------------
5/9
45 = F - 32
+32 +32
------------------
77=F
