The table below brings the time spent (in minutes) on the graded practice exam 1 and the scores of 10 randomly selected ECN 221 online students. Calculate the \( Z \) score when the time spent is equal to 40 minutes. Use variance \( =135.73 \) Use FOUR decimal places, and include the zero before the decimal place or the MINUS sign when needed. E.g., \( -0.1234 \). No credit will be given for rounding mistakes.
