Question

The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of

98.38°F

and a standard deviation of

0.63°F.

Using the empirical rule, find each approximate percentage below.

a.	What is the approximate percentage of healthy adults with body temperatures within 1 standard deviation of the mean, or between 97.75°F and 99.01°F?
b.	What is the approximate percentage of healthy adults with body temperatures between 97.12°F and 99.64°F?

a. Approximately____of healthy adults in this group have body temperatures within

standard

deviation

of the mean, or between

97.75°F

and

99.01°F.

(Type an integer or a decimal. Do not round.)

b. Approximately____of healthy adults in this group have body temperatures between

97.12°F

and

99.64°F.

(Type an integer or a decimal. Do not round.)

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
