A field trial was conducted to assess the effect of irrigation with saline water on the growth of a commonly used pasture species thought to be salt tolerant. 12 plots in total were available for this experiment and it was proposed to irrigate these plots with water containing 4 different concentrations of salt. The treatments were to be equally replicated. At the end of a 4 month growing season all the plots were to be harvested and the dry matter yield of each plot recorded. Referring to this scenario select the correct statement(s). Ho: the dry matter will be all equal among the different salinity level. Ho: the dry matter will be all not all equal among the different salinity level. HA: the dry matter will be all equal among the different salinity level. HA: the dry matter will be not all equal among the different salinity level. HA: the dry matter will be all different among the different salinity level
