Assume that a sample is used to estimate a population mean μ. Find the 99.9% confidence interval for a sample of size 47 with a mean of 84.7 and a standard deviation of 19.3. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). 99.9% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
