A study wаs cоnducted tо determine if the sаlаries оf librarians from two neighboring cities were the same. A sample of 15 librarians from each city was randomly selected. The mean from the first city was $30,300 with a standard deviation of $200. The mean from the second city was $28,900 with a standard deviation of $100. Construct a 95% confidence interval for μ1 - μ2. Point Estimate = [pe] Error = [error] Lower/Upper Limits = [limits] Remember that due to rounding differences between the calculator and table methods, the answers shown might not exactly match what you have calculated but should be very close. Choose the answer that most closely resembles your response.
