In the article “Fatigue Testing of Condoms”, the investigators developed a new test of condoms that adds cyclic strain to a level well below breakage and determines the number of cycles to break. A sample of 20 condoms of one particular type resulted in a sample mean of 1,584 cycles and a sample standard deviation of 607 cycles.

Construct a confidence interval at the 99% confidence level for the true average number of cycles to break. You can assume the population follows a normal distribution.

4. In the article “Fatigue Testing of Condoms", the investigators developed a
new test of condoms that adds cyclic strain to a level well below breakage and determines
the number of cycles to break. A sample of 20 condoms of one particular type resulted
in a sample mean of 1,584 cycles and a sample standard deviation of 607 cycles.
Construct a confidence interval at the 99% confidence level for the true average number
of cycles to break. You can assume the population follows a normal distribution.

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 + ...
