To solve the problem step by step, we will analyze the information given and derive the necessary equations to find the values of \( n \) and the mean. ### Step 1: Understanding the Sum of Deviations from 50 We know that the sum of deviations of a set of values \( x_1, x_2, x_3, \ldots, x_n \) from 50 is -10. This can be expressed mathematically as: \[ \sum_{i=1}^{n} (x_i - 50) = -10 \] This expands to: ...
