Answer:
The solution is (-∞, 0.125) ∪ (0.18,∞)
Step-by-step explanation:
we have
This is a compound inequality
or 
Remember that
so
-----> the solution is the interval (0.18,∞)
----> the solution is the interval (-∞, 0.125)
The solution of the compound inequality is
(-∞, 0.125) ∪ (0.18,∞)

Answer:
c) 95% of all random samples of customers will show that 82% to 94% oders arrive on time
Step-by-step explanation:
From problem statement we take 88 as a mean of a normal distribution, in that case we know, about relation between mean and standard deviation
μ ± σ ⇒ [ μ - σ ; μ + σ ] ⇒ [ 88 - 6 ; 88 + 6 ] ⇒ [ 82 ; 94 ]
The above mentioned interval get 95.7 % of all values for a normal distribution, so we must be sure that a 95 % of all random samples of customers will show that 82% to 94% of orders arrive on time
