Fevers above 39°C can be serious and may require medical treatment. However, doctors don't usually recommend treatment for a mild fever of 38–39°C.Explain why doctors would have this recommendation.

Fill in the blank question.A fever, an increase in body temperature, often accompanies an infection. The body responds in such a manner to the rates of defensive reactions that kill bacteria.

Read the passage.How Fevers HelpFevers can be uncomfortable, but the upside is that they are evidence of the body's attempt to heal. When a person develops an infection, a section of the brain called the hypothalamus recognizes a threat. The hypothalamus responds by increasing the body's temperature. Since both viruses and bacteria are temperature sensitive, this environment helps prevent them from multiplying. In addition, scientists have found evidence that fevers may increase the number of certain lymphocytes—white blood cells that are part of the immune system. Increased lymphocytes make the body more effective in destroying infected cells. Of course, this doesn't mean that high fevers don't warrant medical treatment. In fact, another reason that fevers are beneficial is that they serve as warning signs, indicating that something is amiss.What is the main, or central, idea of the passage?Fevers are useful because they help the body fight infections.Fevers are useful because they increase the body's lymphocytes.The hypothalamus responds to infections by raising the body's temperature.Submit

Five patients entering a hospital with a high fever were selected at random and were administered a new drug which is designed to reduce fever. The body temperature (°F) of each patient was measured before the new drug was administered and 2 hours after the administration. The data are given in the following table.Patient 1 2 3 4 5Before 103 99 102 101 103After 100 99 98 100 100 Assume the differences between before and after measurements follow a normal distribution. Let μ1 denote the mean body temperature of high fever patients before taking the new drug and let μ2 denote the mean body temperature of high fever patients after taking the new drug. Also let μD = μ1 - μ2. Suppose we want to test whether the new drug is effective in reducing fever at the 5% level of significance. What is the test statistic for this test?Question 3Select one:a.Z=X¯−μσ/n√𝑍=𝑋¯−𝜇𝜎/𝑛 b.T=X¯1−X¯2−(μ1−μ2)S21n1+S22n2‾‾‾‾‾‾‾‾√𝑇=𝑋¯1−𝑋¯2−(𝜇1−𝜇2)𝑆12𝑛1+𝑆22𝑛2 c.T=X¯1−X¯2−(μ1−μ2)S2pn1+S2pn2‾‾‾‾‾‾‾‾√𝑇=𝑋¯1−𝑋¯2−(𝜇1−𝜇2)𝑆𝑝2𝑛1+𝑆𝑝2𝑛2 d.T=D¯−μDSD/n√

Multiple Choice QuestionAn infection is often accompanied by an increase in body temperature, or fever. What is the kinetic role of fever in fighting infection?Multiple choice question.Increased body temperature inhibits the biochemical reactions of bacteria.An increase in body temperature alerts the patient to the presence of the infection.Increased body temperature increases the rates of the body's defensive reactions.
