Estimation
A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.
Question
**Finding Degrees of Freedom and Critical Values for Confidence Intervals** Use the given information to find the number of degrees of freedom, the critical values \( \chi_{L}^2 \) and \( \chi_{R}^2 \), and the confidence interval estimate of \( \sigma \). It is reasonable to assume that a simple random sample has been selected from a population with a normal distribution. - **Information Provided:** - **Platelet Counts of Women 90% confidence** - **Sample Size (\( n \)):** 26 - **Sample Standard Deviation (\( s \)):** 65.9 Click the icon to view the table of Chi-Square critical values. - **Degrees of Freedom (\( df \)):** - \( df = \square \) (Type a whole number.) The image includes a blue icon, suggesting an interactive element for viewing the Chi-Square critical values table. This graphical element typically helps users find critical values needed for further calculations.
