Problem: Write an article based on this summary: Calculate the mean.

Answer: Add up all the numbers and divide by the population size: Mean () = X/N, where is the summation (addition) sign, xi is each individual number, and N is the population size. In the case above, the mean is simply (12+55+74+79+90)/5 = 62.

Answer: You'll find it in the Applications folder. Excel for macOS cannot import XML data from another source, but it will allow you to open XML spreadsheet files. It's at the top of the screen. This opens a Finder window. To do this, browse to the folder where it's contained, then click the file name once. The contents of the XML file will appear. The XML file is now saved as a .CSV on your Mac.

Problem: Write an article based on this summary: Locate an exposed metal screw or bolt on the car's frame. Scrape away any paint around the bolt. Strip 12in (1.3cm) off the ground wire before installing it. Slip the wire into a ring terminal and attach it to the bolt.

Answer: Try looking near the rear tires for a bolt near the sides. You may need to pull back the carpeting to get a view of it sticking up from the wheel well. The ground wire routes excess electricity away from your sound system. Take advantage of any accessible metal components to keep your system safe. If your vehicle doesn't have a contact point, you can install one. Use a masonry bit to drill through the metal, then insert a screw or bolt. Make sure you don't drill through anything other than the metal! Sometimes, the bolt is located on a small platform that has been painted over. The paint prevents the ground wire from making a good connection to the wire. Use a paint scraper to gradually remove all of the paint surrounding the bolt. You don't have to eliminate all of the paint, only the material around the bolt. When you install the ground wire, you will be able to see where it rests on the panel. Remove any paint underneath the ring connector. The ground wire is usually black and much shorter than the other connecting wires. Use wire strippers again to take the insulation off one end, then crimp the exposed threads together. Leave the uncut end of the wire inside the trunk for now. Make sure the wire strands are firmly wrapped together so they fit well inside a connector. If the wire doesn't do its job, it could blow out your system or shock you. Plug the wire into the opening on the terminal. Push it all the way into the terminal until you see the wire come into contact with the ring. Then, place the ring onto the bolt to install it. Your wire kit most likely came with a couple of ring terminals, but you can always buy more from a hardware store. Consider placing a lock or star washer on top of the ring terminal to keep it pinned in place. One of the most common problems with subwoofers and amps is when the terminal doesn't have full contact with the bolt or screw.

Answer:
Hamsters like to be awake at night, so the best time to spend time with your hamster is after the sun has gone down. For this reason, hamsters make great pets for night owls. Be aware that if you try to pick up your hamster during the day, it will be more likely to bite you. To help keep your hamster happy and healthy, you will need to keep his cage nice and clean. Once per week you should also perform a deep cleaning on your hamster's cage. Remove everything from your hamster's cage (including your hamster) and scrub the sides and bottom with warm, soapy water. Then rinse and dry the cage before putting in new bedding, your hamster's accessories, and your hamster. In addition to a weekly deep clean, you should also do the following every day: Remove and replace any soiled or damp bedding. Remove and dispose of droppings. Check the corners of your hamster's cage for hidden food. Hamsters have a tendency to stash food for later. It will take some time and patience before your hamster is ready to let you hold him. Build up his trust in you by allowing him to sniff your hand and even give you a little nibble. You can also offer your hamster a treat from your hand to build up his trust in you. Once your hamster is comfortable with you, you can try to pick him up. To pick up your hamster, gently cup both hands around him and lift him slowly out of his cage. Do not swoop in and grab him or you will startle him and cause him to hide from you. Hamsters also need time outside of their cages to be happy. Once you have established trust with your hamster, take him out of his cage once per day for a little supervised playtime outside of his cage. Make sure to keep him in a room where you can monitor his movement. Otherwise he might hide somewhere and make it difficult for you to find him. Make sure that there are no hazards in the area, such as electrical cords, that your hamster might gnaw on. A healthy hamster will be much happier than an unhealthy hamster. If a hamster is well cared for, it may live to be 1-2 years old. Take your hamster for regular check-ups with the veterinarian to make sure that he stays healthy and happy. An unhealthy hamster may have a variety of symptoms, such as dull-looking eyes, matted fur, weight loss, shaking, runny nose and diarrhea. If your hamster is sick, take him to see a veterinarian right away. Hamsters can catch the common cold from humans. If you are sick, avoid holding your hamster until you are well again so that you don't make him sick.
