Esparanza rolls a number cube and gets a six 8 times. based on this experiment, she predicts that if she rolls the cube 1,600 times, she would get a six 640 times. how many times did she roll the number cube in her experiment? explain your reasoning

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
