Fifty-three percent of U.S households have a personal computer. In a random sample of 250 households, what is the probability th

aleksley [76]

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) = $\sqrt{\frac{p(1-p)}{n} }$ = $\sqrt{\frac{0.53(1-0.53)}{250} }$ = 0.0316

For x = 120, sample proportion(p) = $\frac{x}{n}$ = $\frac{120}{250}$ = 0.48

So, likelihood that fewer than 120 have a PC

= P(x < 120)

= P( p^ < 0.48 )

= P(z < $\frac{0.48-0.53}{0.0316}$ ) (z= $\frac{p^-p}{SE}$ )

= P(z < -1.58)

= 0.0571 ( From normal table )

When performing the ipconfig command, what does the following output line depict if found in the tunnel adapter settings?

Andrew [12]

Answer:

d. IPv4 Address 192.168.0.4 is associated with the globe IPv6 address 2001:db8:0:10:0:efe

Explanation:

The adapter setting will be associated with the global IP address. When Ipconfig command is operate the IP address finds the relevant domain and then address will use a different subnet. The network will use both IPv4 and IPv6 subnets in order to execute the command.
