Determine the confidence level for each of the following lar

Determine the confidence level for each of the following large-sample one-sided confidence bounds. (Round your answers to the nearest whole number.) Upper bound: x + 0.84s/ square root n % Lower bound: x - 1.88s/ square root n % Upper bound: x + 0.52s/ square root n % You may need to use the appropriate table in the Appendix of tables to answer this question. Reported that, in a study of a particular wafer inspection process, 356 dies we by an inspection probe and 235 of these passed the probe. Assuming a stable 95% (two-sided) confidence interval for the proportion of all dies that pass answers to three decimal places.) ( , )

Solution

a) 30% conf level

b) 3% level

c) 19.85%
