The force of repulsion, F newtons (N), between two particles is inversely proportional to the square of
the distance, d m, between the particles.
(i) Write down a formula connecting F and d.
(ii) When the particles are a certain distance apart,
the force of repulsion is 20 N. Find the force
when the distance is halved.

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
