Question
Plant X is just like an ordinary plant in its infancy. After six months, however, there is a chance that it will develop a pink tint in all of its leaves. Laura is an amateur biologist who loves the colour pink and has developed a particular chemical formula designed to increase the chances that Plant X will develop this tint after six months. In order to test whether this formula works, she sets up an experiment whereby 50 such plants are allowed to grow normally, and another 50 are given her special formula. After a bit over six months, she records her observations in her diary. However, before she could do any testing on the data, her pet dog ate chunks out of her diary, leaving her with only a fraction of her initial observations. To make matters worse, her dog ate some of the plants as well! The following data was all she could recover from the remnants of her diary: Being knowledgeable in statistics and two-way tables, you offer to help her finish her experiment. Laura wishes to know the proportion of formula-administered plants that developed the pink tint. Calculate this proportion using all the data given. Give your answer as a whole percentage. Proportion = %Explanation / Answer
proportion=25/50=0.5~50%
please reply
normal formula Total no tint 50-20=30 55-30=25 55 pink tint 50*0.4=20 45-20=25 100-55=45 total 50 50 100
