Ally is making a scale diagram of her classroom. she uses a scale factor of 3 centimeters per foot to draw the diagram. the actual length of the classroom is 18 feet, and its width is 20 feet. what is the area of the scale drawing of the classroom?

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
