Is this relation a function? justify your answer A. No, because two points with the same y-value have different x- values.
B. yes, because every x-value corresponds with a single y-value.
C. Yes, because every x- and y-value is positive.
D. Yes, because the number of x-value is the same as the number of y-values.

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
