Amasonry contractor is preparing an estimate for building a stone wall and gate. he estimates that the job will take a 40-hour work week. he plans to have three laborers at $14 per hour and six masons at $24 per hour. he'll need $3143 worth of materials and wishes to make a profit of $500. write a mathematical statement that will give the estimated cost of the job. then calculate this total.

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
