Directions Answer the following questions. You may use StatCrunch to perform your calculations. 1. Assume that human body temperature is normally distributed with a mean of µ = 98.20°F and standard deviation o = 0.62°F. a. A hospital uses 100.6°F as the lowest temperature to be considered a fever. What percentage of healthy people would be considered to have a fever under this definition? Does this percentage suggest that the cutoff of 100.6°F is appropriate? b. Several physicians at this hospital want to lower the cutoff temperature of 100.6°F. What should the temperature be lowered to if they want only 5% of healthy people
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
