The production of pasture grass for hay is an important agricultural product.  A new type of grass, called Teff Grass is advertised to produce 2 ton of hay per acre on the first cutting.  Twenty-five test plots of this new grass resulted in average production of 1.92 ton per acre on the first cutting with a standard deviation of 0.40 ton.  Assume that the production of hay is a normally distributed random variable, which is a necessary assumption with this small sample. 

1. What is the name of the distribution of the test statistic if the mean hay production is 2tons?
