1st question : how to study for chem applications
you should be given a cie booklet , or you could download the cie booklet from the alevel site. i suggest reading through it and hitting the past paper right after. there is 3 booklets, biochem, materials and design and analytical chem. besides biochem and materials. there are many books available which contain analytical chem practices which you could use as well. i could help you if you have a specific topic on chem apps.
2nd Question: Explain as much as you can continuity correction ; when to apply it; hw to apply it
continuity correction is a means of standardizing after a bionomial expression. so after a bionomial expression if the question asks, use an appropriate approx to ....... , form the bionomial expression you do np=mean npq =standard deviation . the p(x>t) should also be given. that value of t is where you apply the continuity correction . for value of p(x>&=t) you use t-0.5 as your x value and for values of p(x>t) you use t+0.5 as your x value. thus from there you deduce your normal dist expression . hope that helps, pm me if you still have issues with it
