Analyze Manda’s work. Is she correct? If not, what was her mistake?

Yes, she is correct.
In step 2, she needed to multiply both sides by 10.
In step 3, she did not subtract one x from the left side.
In step 4, she did not simplify her fraction.

1. x=0.27272727273
2. 100x=27.2727272
3. 100x= 27
4. x=27/100

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
