Question
In the Panhandle, and off the Caprock, cattle-grazing is an important business. Here, cattle graze on native grasses like blue grama and saddleoats grama. In areas where pinyon pine and various junipers grow (esp. one-seeded Juniper), native grasses, such as blue grama, have been reported either to be stunted in, or to be absent from, the immediate vicinity of these plants. Lack of blue grama growth is correlated with accumulation of leaf liter from these coniferous specie (Jameson, 1966). 7. Describe a testable hypothesis to account for these observations about blue grama growth near pinyon pine trees: If: then:Explanation / Answer
For testing a hypothesis there should two statements,one is the null hypothesis(H0) and other one is alternative hypothesis(H1). Null hypothesis is assumed to be true statement regarding the contest. alternative hypothesis is that one which contradicts the null hypothesis by stating the actual value of population parameter is not equal to the value stated in the null hypothesis.
Here the blue grama growth near the pinyon pine trees are absent. So the testable hypothesis can be;
If the pinyon pine trees are present, then the population of blue grama will be insignificant.
