The Pew Research Center Internet Project conducted a survey of 857 Internet users. This survey provided a variety of statistics

lana [24]

Answer:

a) 95% confidence interval for the proportion of respondents who say the Internet has been a good thing for them personally:

$0.8801\leq \pi \leq 0.9199$

b) 95% confidence interval for the proportion of respondents who say the Internet has strengthened their relationship with family and friends:

$0.6386\leq \pi \leq 0.7014$

c) 95% confidence interval for the proportion of Internet users who say online groups have helped solve a problem:

$0.5267\leq \pi \leq 0.5933$

Explanation:

a) We have a sample proportion of 90% (p=0.90).

The sample size is n=857.

For a 95% CI, the z-value is z=1.96.

The standard deviation for the proportion is:

$\sigma_p=\sqrt{\frac{p(1-p)}{n}}= \sqrt{\frac{0.9*0.1}{857}}=0.0102$

Then the upper and lower limit of the 95% CI is:

$LL=p-z\cdot \sigma_p=0.9-1.96*0.0102=0.9-0.0199=0.8801\\\\UL=p+z\cdot \sigma_p=0.9+1.96*0.0102=0.9+0.0199=0.9199$

b) We have a sample proportion of 67% (p=0.67).

The sample size is n=857.

For a 95% CI, the z-value is z=1.96.

The standard deviation for the proportion is:

$\sigma_p=\sqrt{\frac{p(1-p)}{n}}= \sqrt{\frac{0.67*0.33}{857}}=0.0160$

Then the upper and lower limit of the 95% CI is:

$LL=p-z\cdot \sigma_p=0.67-1.96*0.0160=0.67-0.0314=0.6386\\\\UL=p+z\cdot \sigma_p=0.67+1.96*0.0160=0.67+0.0314=0.7014$

c) We have a sample proportion of 56% (p=0.56).

The sample size is n=857.

For a 95% CI, the z-value is z=1.96.

The standard deviation for the proportion is:

$\sigma_p=\sqrt{\frac{p(1-p)}{n}}= \sqrt{\frac{0.56*0.44}{857}}=0.0170$

Then the upper and lower limit of the 95% CI is:

$LL=p-z\cdot \sigma_p=0.56-1.96*0.0170=0.56-0.0333=0.5267\\\\UL=p+z\cdot \sigma_p=0.56+1.96*0.0170=0.56+0.0333=0.5933$

In your opinion, discuss of the importance of having a business website. And also their advantage and disadvantage.

azamat

Answer:

The first and perhaps most obvious advantage of a business website is the potential for reaching a wider audience. The internet is used by literally millions of people, all of them are looking for something and some of them might be looking for you!

Building a website for your business will mean you could potentially reach these otherwise unreachable customers. Your business might be local, but you might have the potential to sell your products or services to a wider market, whether it be people in the next town, the nation as a whole or even the international market. Data shows that internet shopping is still on the rise, so taking your business online will potentially allow you to take advantage of the growth and expand your business. Even if you have no intention of using a business website to sell, you still might want to let customers know about your business. People commonly research businesses online before actually visiting the business location. So having a well designed website will help encourage them to come and visit you or be able to find your business in the first place.

Disadvantages of a Business Website

There are a few disadvantages of having a website for your business. Generally though, they are outweighed by numerous advantages.

Anna35 [415]

Economic resources are scarce, making each consumer face an individual budget constraint. So consumers should make choices that maximize their satisfaction in the face of their budget constraints. To make the choices, consumers use their preferences. In this matter, the student organization resources available for hiring speakers is $ 20,000. That means their budget constraint is $ 20,000. Then, they should choose, from the speakers that cost up to this value, the one that generates the greatest benefit for the student group. This is a choice based on group preferences.
