a 12-ounce can of Fizzy cola has a mean volume of 12 oz, with a standard deviation of 0.25 oz. Harry opens a can and measures and finds he has less than 11.5 oz of cola. What's the probability of this occurring

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
