As a result, the Boston public school district claimed that the schedule adjustment was an improvement-students were not as late. Assume a population standard deviation for bus arrival time of 12 minutes. The value of the test statistic is ________.

• A) t₃₅ = -2.00
• B) z = -2.00
• C) t₃₅ = -0.33
