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:
where are data points, is the mean and n is the number of observations.
Sum of squares of differences = 12730
Thus, the sample mean is 127.33 kN and sample standard deviation is 26.59 kN.
