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

are confidence intervals? It is explained as a range of values so defined that there is a specified probability that the value of a parameter lies within it. The next question to be asked is how we form a confidence interval. The purpose of taking a random sample from a lot or population and calculating a statistic‚ such as the mean from the data‚ is to estimate the mean of the population. How well the sample statistic estimates the underlying population value is always an issue. A confidence interval

Confidence Intervals Consider the following question: someone takes a sample from a population and finds both the sample mean and the sample standard deviation. What can he learn from this sample mean about the population mean? This is an important problem and is addressed by the Central Limit Theorem. For now‚ let us not bother about what this theorem states but we will look at how it could help us in answering our question. The Central Limit Theorem tells us that if we take very many
