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 )

_____ allow you to logically separate ports in switches to create subdomains without wiring your network as physical subdomains.
AlladinOne [14]

Answer:

The correct answer for the following question is VLAN.

Explanation:

It stands for Virtue Logical Area Network which allows you to group port on a switch logically. VLANs can be extend across (a period of time) multiple switches means you used to express on port that you're in that VLAN by changing the VLAN number.

We have the ability to improve our security with VLANs by controlling what VLAN is accessing with the other network of VLANs. So that this network is particularly helpful in office situation to create subdomain without wiring physical domain as your network.

This semester we looked at three languages (C++, Java and Python). One common rule in all three class checklists (for C++, Java
Marysya12 [62]

Answer:

The languages C++, Java, Python are Object Oriented Programming languages. What this means is that we create classes and then instantiate those classes. In C++ and Java, we use the new operator to instantiate the classes. So, if we want to display some data when we try to print the instance just like we print the variables of data types like int, double, string etc, we need to define what we need to display. It is because, class are just like data types like int, double etc. But as they are defined by the developer according to his/her needs, so the developer has to define what to print when they are printed.
