The production of pasture grass for hay is an importantagricultural product. A new type of grass, called Teff Grass isadvertised to produce 2 ton of hay per acre on the first cutting.Twenty-five test plots of this new grass resulted in averageproduction of 1.92 ton per acre on the first cutting with astandard deviation of 0.40 ton. Assume that the production of hayis a normally distributed random variable, which is a necessaryassumption with this small sample.
