Question

Assume that you have just accepted a position as chief scientist for a leading agricultural company. Your first assignment is to make a recommendation concerning the best type of grass to grow in the Pacific Northwest and the best fertilizer for it. You fertilize three different types of grass with two different kinds of fertilizer and determine the number of grass blades per square inch of area where the grass is planted. Your recommendation is based on the density of the grass--the denser the grass is, the better.

Explanation / Answer

With the given data, the easiest way to know the best type of grass and fertlizer for it is by calculating the mean of grass blades per square inch.

Mean density of type I with Red Fescue = (14+15+16+17+10)/5 =14.4 per sq. inch

Mean density of type II with Red Fescue = 10.2 per sq. inch

Mean density of type I with Kentucky Blue = 14.6 per sq. inch

Mean density of type II with Kentucky Blue = 9.8 per sq. inch

Mean density of type I with Green Velvet = 20.2 per sq. inch

Mean density of type II with Green Velvet = 14.6 per sq. inch

So, Type I grass with Green Velvet is the best option
