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 this sample.
Homework Answers
Test statistic =
= (
- 
) / s / 
n
= (98.4 - 98.6) / 0.35 /
50
Test statistic = -4.0406

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.)
What is normal, when it comes to people's body temperatures? A random sample of 130 human body temperatures had a mean of 98.15° and a standard deviation of 0.74°. Does the data indicate that the average body temperature for healthy humans deviates from 9
Test using the p-value approach with ? = 0.05.State the null and alternative hypothesis.H0: ? < 98.6 versus Ha: ? > 98.6H0: ? = 98.6 versus Ha: ? > 98.6 H0: ? = 98.6 versus Ha: ? < 98.6H0: ? = 98.6 versus Ha: ? ≠ 98.6H0: ? ≠ 98.6 versus Ha: ? = 98.6Find the test statistic and the p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.)z=p-value=State your conclusion.The p-value is greater than alpha so H0 is not rejected. There is insufficient evidence to indicate that the average body temperature for healthy humans deviates from 98.6°.The p-value is less than alpha so H0 is rejected.

It has long been reported that human body temperature follows a normal distribution with a mean of 98.6 degrees Fahrenheit. There is some debate in the medical field, however, about this long-held standard of human body temperature. Specifically, some medical researchers believe that the average human body temperature is actually greater than 98.6 degrees Fahrenheit. To test their theory, these researchers measured the body temperature of a random sample of 180 healthy individuals. The researchers then recorded the mean and...

It has long been stated that the mean temperature of humans is 98.6°F. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6°F. They measured the temperatures of 42 healthy adults 1 to 4 times daily for 3 days, obtaining 196 measurements. The sample data from those 196 measurements resulted in a sample mean of 98.4°F and a sample standard deviation of 0.9°F. Use the P-value approach to conduct a hypothesis...

A data set includes 103 body temperatures of healthy adult humans for which x=98.3 F and s=0.73 F. A.)What is the best point estimate of the mean body temperature of all healthy humans? The best point estimate is ? degrees F. B.)Using the sample statistics, construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. Do the confidence interval limits contain 98.6 degreesF? What does the sample suggest about the use of 98.6 degrees F...
