- Construct the indicated confidence interval for the difference between the two population means. Assume that the two samples are independent simple random samples.Independent samples from two different populations yield the following data. x̅1 = 393, x̅2 = 703, s1 = 85, s2 = 98. The sample size is 348 for both samples. Find the 90% confidence interval for μ1 - μ2.Find the critical value x²R corresponding to a sample size of 19 and a confidence level of 99 percent. X²R = (Round to 3 decimals)A sample size of 100 from a population having a standard deviation =8 produced a mean of 40. The 99% confidence interval for the population mean (rounded to two decimals) is:
