An article in the Journal of Structural Engineering (Vol. 115, 1989) describes an experiment to test the yield strength of circu

gladu [14]

Answer:

The sample mean is 127.33 kN and sample standard deviation is 26.59 kN.

Step-by-step explanation:

We are given the following in the question:

97, 97, 102, 102, 102, 103, 103, 108, 127, 127, 129, 129, 141, 159, 164, 164, 164, 174

Formula:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{2292}{18} = 127.33$

Sum of squares of differences = 12730

$s = \sqrt{\frac{12730}{17}} = 26.59$

Thus, the sample mean is 127.33 kN and sample standard deviation is 26.59 kN.
