Question
### Population Mean Estimation Using Confidence Intervals **Scenario:** Salaries of 49 college graduates who took a statistics course in college have a mean (\(\bar{x}\)) of $69,300. Assuming a standard deviation (\(\sigma\)) of $10,729, construct a 99% confidence interval for estimating the population mean (\(\mu\)). **Resource Links:** - [Click here to view a t distribution table.](#) - [Click here to view page 1 of the standard normal distribution table.](#) - [Click here to view page 2 of the standard normal distribution table.](#) **Task:** Calculate the 99% confidence interval for the population mean (\(\mu\)) and fill in the corresponding values in the boxes below. Round to the nearest integer as needed. \[ \$\ \Box \ \ < \ \mu \ < \ \Box \ \ ] --- **Explanation of Links and Diagrams:** - **t distribution table**: A table that provides critical values for the t-distribution, used when constructing confidence intervals and conducting hypothesis tests. - **Standard normal distribution table (Page 1 and Page 2)**: Tables that provide cumulative probabilities and z-scores for the standard normal distribution, useful for finding probabilities and critical values associated with normally distributed data.
