McNeese and Klein (1991) looked at the average particle size. Specifications give the standard deviation of 2 microns. A sample of 25 particles in microns is given here103.8, 95.3, 96.7, 96.8, 102.3, 93.8, 99.6, 96.9, 105.8, 92.1, 101.5, 100.6, 101.6, 102.8, 97.8, 104.7, 102.7, 94.9, 100.9, 100.5, 102.7, 103.2, 97.5, 98.3, 94.9Conduct the most appropriate hypothesis test to test the accuracy to specification of production using 5% significance level. Construct a 95% confidence variance interval and standard deviation interval. Interpret each interval. Are you comfortable with your assumptions for this analysis? Explain and provide graphs to support your position.

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?
