Step 1

To calculate the squared deviation for each value, we subtract the mean (X) from each value (x) and then square the result. For the value 0: (0 - 2.19)^2 = 4.7961 For the value 1: (1 - 2.19)^2 = 1.3761 For the value 2: (2 - 2.19)^2 = 0.0361 For the value Show more…

Calculate the standard deviation from the sample of the number of children per family in the given table: Number of children Number of families 0 345623 1 16 2 22 14 1 Note: Sample standard deviation is equal to the mean for this table, which is 2.19. S = √(Σ(x - X)^2 * f / (n - 1)) Please note that the formatting of the equation may not be accurately represented here.
