R.017 cans sold in the area were One approximation. Round your answers to p did a study of recycling habits in a California community. It found that 72% of the four decimal places.) (a) Ir 397 cans are sold today, what is the probability that 300 or more will be recycled? (b) or the 397 cans sold, what is the probability that between 260 and 300 will be recycled? 1 9 2 3

Explanation / Answer

a) mean =np=397*0.72=285.84

and std deviation=(np(1-p))1/2 =8.9462

therefore P(X>=300)=P(Z>(299.5-285.84)/8.9462)=P(Z>1.5269)=0.0634

b)

P(260<X<300)=P(-2.8324<Z<1.5269)=0.9366-0.0023 =0.9343
