Aprocessor of carrots cuts the green top off each carrot, washes the carrots, and inserts six to a package. twenty packages are inserted in a box for shipment. each box of carrots should weigh 20.4 pounds. the processor knows that the standard deviation of box weight is 0.5 pound. the processor wants to know if the current packing process meets the 20.4 weight standard. how many boxes must the processor sample to be 95% confident that the estimate of the population mean is within 0.2 pound?

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
