Use the given data to find the 95% confidence interval estimate of the population mean μ. Assume that the population has a normal distribution. (Provide your answer with at least three decimal places) IQ scores of professional athletes: Sample size n = 20 Mean x̄ = 103 Standard deviation s = 15

Consider two independent random samples with the following results: n1 = 685, p̂1 = 0.41, n2 = 510, p̂2 = 0.23. Use this data to find the 80% confidence interval for the true difference between the population proportions. Step 3 of 3: Construct the 80% confidence interval. Round your answers to three decimal places. Interval for low and high point.

If n = 10, x̄ = 33, and s = 14, construct a confidence interval at a 90% confidence level. Assume the data came from a normally distributed population. Give your answers to three decimal places. __________ < μ < __________
