Human body temperature is 98.6 degrees, a nurse thinks this is too high, that is the mean body temperature is below 98.6. The nurse obtains a random sample of 106 human body temperatures and finds that the mean for the sample is 98.20 degrees; she assumes the population standard deviation is 0.62 degrees. At an alpha=0.02 test the nurse's claim.

    A data set includes 106 body temperatures of healthy adult humans having a mean of 98.9 degrees and a standard deviation of 0.62 degrees. Construct a 99​% confidence interval estimate of the mean body temperature of all healthy humans. What does the sample suggest about the use of 98.6 degrees as the mean body​ temperature?

  • Assume the temperature of a healthy human body is normally distributed with a mean of 98.6°F...

    Assume the temperature of a healthy human body is normally distributed with a mean of 98.6°F and standard deviation of .6°F. To make the measurements more precise a nurse measures the temperature 4 times and averages the measurements. According to the Central Limit Theorem what is the standard error, which is the standard deviation for the sample mean of the four measurements of temperature? (Express your answer as a decimal number, round to ONE decimal place.)

    Normal body temperature for healthy, at-rest human beings has always been said to be 98.6°F. A doctor has seen a lot of patients who had a lower or higher body temperature when they were not ill. He has read research that says it is actually lower. So, he collected 50 randomly selected temperatures that had a mean of 98.4°F. The standard deviation is known to be .35°F. Ho: μ = 98.6 Ha: μ ≠ 98.6 Calculate the test statistic for...

    Healthy people have body temperatures that are normally distributed with a mean of 98.20 degrees Fahrenheit and a standard deviation of 0.62 degrees Fahrenheit. If a healthy person is randomly selected, what is the probability that he or she has a temperature above 98.8 degrees Fahrenheit? A hospital wants to select a minimum temperature for requiring further medical tests. What should the temperature be, if we want only 2.5% of healthy people to exceed it?

    It has long been stated that the mean temperature of humans is 98.6 degrees F. ​However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6 degreesF. They measured the temperatures of 148 healthy adults 1 to 4 times daily for 3​ days, obtaining 700 measurements. The sample data resulted in a sample mean of 97.7 degreesF and a sample standard deviation of 0.7 degreesF. ​(a) Using the classical​ approach, judge whether...
