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.
Assuming the population of interest is approximately normally distributed, construct a 99% confidence interval estimate for the population mean given the values below. x-18.5 4.3 n-19 The 99% confidence interval for the population mean is from to Round to two decimal places as needed.

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.)
Assuming that the population is normally distributed, construct a 99% confidence interval for the population mean for each of the samples below. Explain why these two samples produce different confidence intervals even though they have the same mean and range. Sample A: 1 3 3 4 5 6 6 8 Sample B: 1 2 3 4 5 6 7 8 Full data set Construct a 99% confidence interval for the population mean for sample A (Type integers or decimals rounded...
Assuming that the population is normally distributed, construct a 99% confidence interval for the population mean, based on e ollowing sample sizeof 1, 2, 3, 4, 5, 6, 7, and 25 In the given data, replace the value 25 with 8 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general. Find a 99% confidence interval for the population mean, using the formula or technology....

A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 115, and the sample standard deviation, s, is found to be 10 (a) Construct a 98% confidence interval about if the sample size, n, s 14 (b) Construct a 98% confidence interval about μ if the sample size, n, is 19 (c) Construct a 99% confidence interval about if the sample size, n, s 14 (d)...
