Explanation:
when you chat to somebody on the Net or send them an e-mail, do you ever stop to think how many different computers you are using in the process? There's the computer on your own desk, of course, and another one at the other end where the other person is sitting, ready to communicate with you. But in between your two machines, making communication between them possible, there are probably about a dozen other computers bridging the gap. Collectively, all the world's linked-up computers are called the Internet. How do they talk to one another? Let's take a closer look! Photo: What most of us think of as the Internet—Google, eBay, and all the rest of it—is actually the World Wide Web. The Internet is the underlying telecommunication network that makes the Web possible. If you use broadband, your computer is probably connected to the Internet all the time it's on.

Explanation:
A sample of 30 households showed that the sample mean of back-to-school spending is $622.85. It is believed that back-to-school spending is normally distributed with a population standard deviation of $65. An analyst wishes to test if the average back-to-school spending differ from $606.40 per family predicted by the trade group at the 5% significance level.
The text editor is not letting me submit my typed answer.Please check attachment
The pvalue is 1.646 which is greater than the level of significance 0.05
This tells us to accept the null hypothesis.
P-value is 0.1646 > significance level.
