THIS IS NOT A GRADED ASSIGNMENT!! An engineer is hired to inspect the condition of blocks used in a façade of a building. The engineer examined a random sample of 52 blocks and found that six had loose connections. These were considered to be failures. What is the point estimate for the proportion of failures? Provide a 95 percent confidence for the true proportion of failures. If the same bounds found for confidence interval in part b must be maintained but at 99 percent confidence, how many additional blocks must the engineer examine?
