To find the sample standard deviation, first calculate the mean of the data set, then use the formula for the sample standard deviation, which involves summing the squared differences between each data point and the mean, dividing by the number of observations minus one, and taking the square root of the result. The correct calculation results in a sample standard deviation of approximately 9.5.
