A recent study states that high winds can affect the pollination rate of sunflowers. It reported that 52 of 60 sunflower plants that were shielded from high winds pollinated and 41 of 55 sunflower plants left unshielded were pollinated. Choose the 98% confidence interval that represents the difference between the proportions of shielded and unshielded sunflower plants that are pollinated. a. [52/60-41/55]+-2.326√(93/115)(93/11 5)(1/60+1/55)
