5. Agricultural scientists are working on developing an improved variety of Roma toma- toes. Marking research indicated that customers are likely to bypass Romas that weigh less than 70 grams. The current variety of Roma plants produce fruit that average 74 grams, but 11% of the tomatoes are too small. It is reasonable to assume that a normal model applies. What is the standard deviation of weights of Romas now being grown? 3.25 alidad 1.23 P = 0.11
