To test the effect of a fertilizer on rice production, 24 equal plots of a certain land are selected. Half of them were treated with fertilizer leaving the rest untreated. Other condition were the same. The mean production of rice on untreated plots was 4.8 quintals with standard deviation of 0.4 quintal. While, the mean yield on the treated plots was 5.1 quital with a standard deviation of 0.36 quintal. Can we say that there is significant improvement in the production rice due to use of fertilizer at 0.05 level of significance? Assume that the variance of population are unknown but not equal.
