Question

Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis?

A scientist claims that the mean incubation period for the eggs of a species of bird is

at least

days.

Does the claim represent the null hypothesis or the alternative hypothesis?
Since the claim
a statement of equality, it represents the
hypothesis.
(a) How should you interpret a decision that rejects the null hypothesis?
There is
evidence to
v the claim that the mean incubation period for the eggs of a species of bird is at least 59 days.
(b) How should you interpret a decision that fails to reject the null hypothesis?
There is
evidence to
the claim that the mean incubation period for the eggs of a species of bird is at least 59 days.

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 + ...
