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 )

Answer: Transceivers
Explanation:
Wireless network adapters differ from regular network adapters because they contain transceivers as, the transceiver is that portion of the network interface which transmitted the data by concerting digital data into the digital signals in the medium. Basically, the network adapter are responsible for connected the host in the network medium and also convert the binary form data.Transceiver signal are basically depends upon the type of the network.
