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]+-2.326β(93/115)(93/11 5)(1/60+1/55)
b. [52/60-41/55]+-2.576β(93/115)(93/11 5)(1/60+1/55)c. [52/60-41/55]+-2.326β(93/115)(93/11 5)(52/60+41/55)d. [52/60-41/55]+-2.326β(52/60(1-52/60 )/60+41/55(1-41/55)/55e. [52/60-41/55]+-2.5766β(52/60(1-52/6 0)/60+41/55(1-41/55)/55

Given: ae β
ce ; de β
be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that β³aeb β
β³ced, we can show that β³ β
β³ceb by. so, β cad β
β by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
