If X overbar=65, S=14, and n=49, and assuming that the population is normally distributed, construct a 99% confidence interval estimate of the population mean, μ.
If X (bar over) = 65, S = 14, n = 49, and assuming that the population is normally distributed construct a 95% confidence interval estimate of the population mean. ( I have the table of critical values for the t distribution but I do understand how to find the solution and plug it in to the formula. Please show all steps and explain how to find it.)

Question Help 8.1.1 Assuming the population of interest is approximately normally distributed, construct a 96% confidence interval estimate for the population mean given the values below. X = 16.9 54.3 ns12 The 95% confidence interval for the population mean is from to (Round to two decimal places as needed. Use ascending order.)
A random sample of size n = 13 obtained from a population that is normally distributed results in a sample mean of 45.2 and sample standard deviation 12.6. An independent sample of size n=17 obtained from a population that is normally distributed results in a sample mean of 51.1 and sample standard deviation 14.9. Does this constitute sufficient evidence to conclude that the population means differ at the a= 0.10 level of significance? Click here to view the standard normal...
