Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
Al Zink actions differentiate him as trying to take an invisible role as a project sponsor. That is, Al Zink does not do his chosen role and accountability as the lead project sponsor. Though, in dissimilar occasions, Al Zink is seen to evade making a serious choice regarding the development of the project. Consequently, as a project sponsor, it is his accountability to deliver clear steps in increasing the project, recover every step of project development and balance the start of the project.
Answer:
All of the above.
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
Hence, the operating system (OS) provides utility software designed to perform specific tasks. Some of the tasks it performs are;
A. Establishing an Internet connection.
B. Coordinating tasks between programs.
C. Configuring peripheral devices.
D. Monitoring security.
