The 5 values needed are:
Min, Q1, Q2, Q3, Max
Order the data:
2, 3, 4, 9, 11, 12, 17, 18
Min= 2, Q1= 3.5, Q2=10, Q3= 14.5, Max=18
The probability is found from a suitable table or probability calculator.
p(z < 1.3) ≈ 0.9031995154
5x+34=-2(1-7x)
Steps:
5x+34=-2+14x
5x+34-14x= -2
-9x + 34= -2
-9x = -2-34
-9x = -36
X= -36/-9
Answer: x= 4
