Question description

Enrollment in a particular class for the last four semesters has been 120, 126, 110,

  and 130 ( listed from oldest to most recent ). Suppose a one-semester moving

  average was used to forecast enrollment ( this is sometimes referred to as a naïve

  forecast ). Thus, the forecast for the second semester would be 120, for the third

  semester it would be 126, and for the last semester it would be 110. What would

  the MSE be for this situation?
