Reference no: EM13113695

A big multinational corporation based in Toronto recently moved it's production facilities to Mexico. When the corporation was in Toronto, it had an older, experienced labour force with a mean age of 45 years. Now that it has moved to Mexico, the company wishes to find out if the average age of the workforce has declined. A sample of 35 employees is selected. The average age is found to be 40 years, with a standard deviation of five years. With a 0.05 level of significance, can we conclude that the mean age of the workforce has declined?
