The temperature inside a room housing computer servers is important to proper function. A Google search for “server room temperature” yields the following (among other results): According to OpenXtra, server room temperatures should not dip below 50 degrees Fahrenheit, and should not exceed 82 degrees Fahrenheit. The optimal temperature range is between 68 and 71 degrees Fahrenheit.
In Lesson 2-4, we learned that Fahrenheit and Celsius temperatures are related by the equation

- In a recent survey, a magazine reported that the preferred room temperature in the summer is 68°F. A wall thermostat, like the ones shown below, tells a room's temperature in degrees Fahrenheit Sarah's Upstairs Bedroom Downstairs Bedroom 72°F 64°F a. Which bedroom is warmer than the recommended room temperature? b. Which bedroom is cooler than the recommended room temperature? c. Sarah notices that her room's temperature is 4°F above the recommended temperature, and the downstairs bedroom's temperature is 4°F below the recommended temperature. She graphs 72 and 64 on a vertical number line and determines they are opposites. Is Sarah correct? Explain. d. After determining the relationship between the temperatures, Sarah now decides to represent 72°F as 4 and 64°F as -4 and graphs them on a vertical number line. Graph 4 and -4 on the vertical number line on the right. Explain what zero represents in this situation.

- The Environmental Protection Agency (EPA) uses a measure called the Pollutant Standards Index (PSI) to measure air quality in a city. A PSI reading over 100 indicates a day when the air quality is considered unhealthy. The measurements represent the number of days in 1995 that the PSI was over 100 for twenty metropolitan areas in the U.S. Midwest. 0, 0, 0, 1, 1, 1, 1, 1, 2, 2, 3, 4, 4, 4, 4, 5, 7, 7, 11, 14 Which of the above is the appropriate boxplot for this data?AB C When we drew the boxplot for this data we found no extreme outliers:truefalsearrow_forwardPlease do not give solution in image formate In the United States, the average baby birth weight is 7 pounds (st. dev = 1). You are a community health care provider working is rural Texas and you are concerned that the pregnant mothers may not be getting the right prenatal care because it seems that their babies are born weighing less than average. In a given rural hospital sample, the mean birth weight is 6.4 pounds for 36 babies this year. Should you be concerned?arrow_forwardSometimes when you are sick, your forehead feels really warm. You might have fever. How can you find out whether you do? By taking your temperature , of course. But what temperature should the thermometer show if your're healthy? Is this temperature the same for everyone? Several years ago, researchers conducted a study to determine whether the "accepted" value for normal body temperature, 98.6oF, is accurate. They used an oral thermometer to measure the temperatures of a random sample of healthy men and women aged 18 to 40. As is often the case, the researchers did not provide their original data. Allen Shoemaker, from Calvin College, produced a data set with the same properties as the original temperature readings. His data set consists of one oral temperature reading for each of the 130 randomly chosen, healthy 18- to 40-year-olds. A dotplot of Shoemaker's temperature data is shown below. A vertical line at 98.6oF was added for reference. Exploratory data analysis revealed…arrow_forward
