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 )
is a small handheld computer that performs simple tasks such as taking notes, scheduling appointments, and maintaining an address book and a calendar PDA.

Answer:
The answer is "Pass the cable into the ceiling instead of over the floor".
Explanation:
Network access explains the complex process of link different parts of the network with each other, e.g. while using switches, routers, and access points, and whether, that system works.
- To replace the cable with a pair cable graded in plenum, covered, twisted.
- We use the cable to pass through the ceiling rather than through the concrete, eliminating the issue and stopping it from occurring again.
