Depends of the negatives info but typically around 7 years
a) ( 0.8509718, 0.8890282)
b) ( 0.7255, 0.7745)
Explanation:
(a)
Given that , a = 0.05, Z(0.025) =1.96 (from standard normal table)
So Margin of error = Z × sqrt(p × (1-p)/n) = 1.96 × sqrt(0.87 × (1-0.87) / 1200)
=0.01902816
So 95 % confidence interval is
p+/-E
0.87+/-0.01902816
( 0.8509718, 0.8890282)
(b)
Margin of error = 1.96 × sqrt (0.75 × (1-0.75) / 1200) = 0.0245
So 95% confidence interval is
p+/-E
0.75+/-0.0245
( 0.7255, 0.7745)
Answer:
By practicing simulated cyber attacks. They help in improving the security and firewall of organization thereby enhancing their resistance to cyber infiltration.
Explanation:
Organizations may often intend to evaluate and their degree of vulnerability and test their security standard, hence, they employ the use of a simulated threat pattern whereby the red team act as a threat by using several infiltration techniques usually used by actual infiltrators, the blue team on the other hand acts to repel the advances of the red team by implementing security protocols and architecture capable of neutralizing the simulated attacks of the red team. This way organizations beef up their security in other to forestall actual potential attacks against capable of invading their information and digital systems.

Answer: Option C
Explanation: In simple words, product focused process refers to the processes that focuses on producing the batch of similar products. These processes are usually used to manufacture products like paper rolls and light bulbs.
Under this process large units are produced of a similar product. Such processes require high fixed cost and low variable cost.
From the above we can conclude that the correct option is C.
