Answer :
To find the sample mean of the given observations on shear strength, we'll follow these steps:
Add all the observations together: We have the following values:
[tex]30.0, 4.4, 33.1, 66.7, 81.5, 22.2, 40.4, 16.4, 73.7, 36.6, 109.9[/tex]
Sum them up:
[tex]30.0 + 4.4 + 33.1 + 66.7 + 81.5 + 22.2 + 40.4 + 16.4 + 73.7 + 36.6 + 109.9 = 515.9[/tex]Count the number of observations: There are a total of 11 observations.
Calculate the mean: Divide the sum of the observations by the number of observations:
[tex]\text{Mean} = \frac{515.9}{11} \approx 46.90[/tex]
Therefore, the sample mean of the given observations is approximately [tex]46.90[/tex] when rounded to two decimal places.
