Answer:
The lower bound of a 99% C.I for the proportion of defectives = 0.422
Step-by-step explanation:
From the given information:
The point estimate = sample proportion 


= 0.55
At Confidence interval of 99%, the level of significance = 1 - 0.99
= 0.01

Then the margin of error 



E = 0.128156
E ≅ 0.128
At 99% C.I for the population proportion p is: 
= 0.55 - 0.128
= 0.422
Thus, the lower bound of a 99% C.I for the proportion of defectives = 0.422
Cost Price for oil change =$27
Charge for the customers =$40
Markup cost = Difference between selling price and cost price =$40-$27=$13
To find the percent of markup, divide the markup cost by the cost price and multiply it by 100.
Markup percent = (13/27)*100
=48.15%

Я бы лучше остался здесь с тобой,
Просто остался здесь с тобой,
Но звезда, что высоко в небе, по-прежнему показывает мой путь.
