T-test Q1. Green Gram Yield Traditionally it is known that a green gram cultivation yields  12.0 quintals per hectare  on an average. To increase crop yields, scientists have developed a new variety of green grams, that can supposedly produce more than the expected average yield of 12 quintals per hectare. To test the same, this variety of green grams was tested on  10  randomly selected farmer's fields. The yield (quintals/hectare) was recorded as:  [14.3,12.6,13.7,10.9,13.7,12.0,11.4,12.0,12.6,13.1] With a  5% significance level , can we conclude that the average yield of this variety of green gra ms is  more  than the expected yield (12 quintals/hectare)? Perform an appropriate test and choose the  correct  option below : A.     p_value = 0.033, Average sample yield is same as expected B.     p_value = 0.049, Average sample yield is same as expected C.     p_value = 0.04...
