#10 Please answer. Use the sample information below and the t-distribution to find a 95% confidence interval for the population mean μ . Assume the underlying distribution is approximately normal. n=10 x¯=125 s=9.4 Round your answers to three decimal places. The 95% confidence interval is
CI on Mean, Variance Known Students on an internship program in the US Fish and Wildlife Service wishes to test the nitrogen content on rivers and waterways in the US Midwest states. 36 sample measurements were taken in various rivers and wate found to be in 2.6 grams per milliliter. Find the 95% and 99% confidence intervals for the mean mercury content. Population standard deviation is 0.3 gram per milliliter. If the students want the error to be less than 0.05, how large a sample size would be required at 95% confidence? Would the required sample size increase if a higher degree of confidence is set?
