machines malfunction. The problem is to compute the 95% confidence interval on π‚ the proportion that malfunction in the population. Solution: The value of p is 12/40 = 0.30. The estimated value of σp is = 0.072. A z table can be used to determine that the z for a 95% confidence interval is 1.96. The limits of the confidence interval are therefore: Lower limit = .30 - (1.96)(0.072) = .16 Upper limit = .30 + (1.96)(0.072) = .44. The confidence interval is: 0.16 ≤ π ≤ .44. Q2. A manager at
