STATISTICAL PRACTICE Homework Question 512.2.40 HW Score: 50%, 3 of 6 points Does a teaspoon of honey before bed really calm a child's cough? To test this folk remedy, pediatric researchers carried out a designed study involving a sample of 105 children who were ill with upper respiratory tract infections. The children, aged 2 to 18 years, were randomly assigned on a single night to one of three treatment groups. One group received a dose of buckwheat honey before bedtime. Unknown to the parents and children, a second group received a dose of dextromethorphan (DM)—an over-the-counter cough medicine while others received no treatment at all. The third group of children received a sweet-tasting placebo. (Also, the honey group actually received a darker type of honey, while the other treatment groups received lighter-colored honeys to help mask any differences.) The next day, parents rated their children's cough symptoms, and the improvement in total cough symptoms score was determined for each child. The data (improvement scores) for the study are shown in the table attached below. Construct a dot plot of the improvement scores for the honey group. a. Construct a dot plot for the coughing improvement scores for the children in the honey dosage group. Choose the correct dot plot below. [Four dot plot options shown] b. What coughing improvement scores occurred most often in the honey dosage group? Type a whole number. Use a comma to separate answers as needed. Clear all Check answers GO BLUE HENS

Foot temperatures: Foot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indicate an increased risk of ulcers. In a study performed at the Colorado School of Mines, skin temperatures on both feet were measured, in degrees Fahrenheit, for 8 diabetic patients. The results are presented in the following table. Use a TI-84 calculator to answer the following. Left Foot Right Foot --- --- 80 80 75 80 85 85 88 86 89 87 78 78 87 82 88 89 Send data to Excel Part: 0 / 4 Part 1 of 4 Compute the least-squares regression line for predicting the right foot temperature from the left foot temperature.

- Growth rate slows following infancy. - MyPlate.gov is a food guidance system that offers an Internet-based tool to provide clients with individualized recommendations for adequate nutrition. Children require the same food groups as adults, but in smaller serving sizes. - Energy needs and appetite vary with the child's activity level and growth rate. - Generally, nutrient needs increase with age. - Attitudes toward food and general food habits are established by 5 years of age. - Increasing the variety and texture of foods helps the child develop good eating habits. - Foods like hot dogs, popcorn, peanuts, grapes, raw carrots, celery, peanut butter, tough meat, and candy can cause choking or aspiration. - Inclusion in family mealtime is important for social development. - Group eating becomes a significant means of socialization for school-age children. TODDLERS: 1 TO 3 YEARS OLD NUTRITION GUIDELINES - Toddlers generally grow 2 to 3 inches in height and gain approximately 5 to 6 lb/year. - Limit 100% juice to 4 to 6 oz a day. - The 1- to 2-year-old child requires whole cow's milk to provide adequate fat for the still-growing brain. - Food serving size is 1 tbsp for each year of age. - Exposure to a new food might be needed 15 to 20 times before the child develops an acceptance of it. - If there is a negative family history for allergies, cow's milk, chocolate, citrus fruits, egg white, seafood, and nut butters can be gradually introduced while monitoring the child for reactions. - Toddlers prefer finger foods because of their increasing autonomy. They prefer plain foods to mixtures, but usually like macaroni and cheese, spaghetti, and pizza. - Regular meal times and nutritious snacks best meet nutrient needs. - Snacks or desserts that are high in sugar, fat, or sodium should be avoided. - Children are at an increased risk for choking until 4 years of age. - Avoid foods that are potential choking hazards. Always provide adult supervision during snack and mealtimes. During food preparation, cut small, bite-sized pieces that are easy to swallow to prevent choking. Do not allow the child to engage in drinking or eating during play activities or while lying down.

To simulate the night sky, we will be using the software Stellarium, which is free and easy to download/install. Go to the following link: https://stellarium.org/ and click on the platform you're using (Windows/Mac/Linux etc.) to install Stellarium. If you want to use the web version of Stellarium, consult the pdf document "How to Navigate in Stellarium-Web" in the sub-module. After you install and open Stellarium, you'll immediately find yourself with a view of the sky as seen from a field at the date time of your class. Stellarium sets the starting location to be Paris, France, so you'll need to change the starting location to NYC. If you move the mouse around the screen, you'll find two menu bars, one on the lower-left hand side of the screen, and another on the bottom of the screen. On the left-hand side menu, scroll over the options until you find the location option. Click on this a pop-up window appears with a world map. A red arrow shows your location as well as your latitude longitude. On the right hand side of the world map is a list of locations in Stellarium. Type New York into the search box a list of locations in New York state will appear in the list. Click on New York (sometimes it reads New York City, NY). Make sure the arrow changes position on the world map. Write down the numbers in the 'Latitude' and 'Longitude' boxes for your location (NYC). To make things easier to see near the horizon, you'll want to switch the landscape to get rid of the houses and trees that show up by default. To do this, move the mouse to the left-hand side menu and select "Sky and Viewing Options" In the window that
