1. A test was done on two groups papaya. The first group were cultivated without using fertilizer while the second group used it. 10 papayas were harvested at random from the first group. 12 papayas were harvested at random from the second group. The mean weight of the first group of papayas was 275g with a standard deviation of 30g. The second group's mean weight is 282g with a standard deviation of 44g. Is there a significant difference between the weights at 5% significance level
