Finding critical value on ti 84.
This is the critical value. Compare the absolute value of each residual value in [L3] to 7.64. If the absolute value is greater than 7.64, then the (x, y) corresponding point is an outlier. In this case, none of the points is an outlier. To obtain estimates of y for various x-values: There are various ways to determine estimates for "y.

Key Steps. In Problem 1, students explore the characteristics of the F distribution. Then they will determine whether the graph changes when the degrees of freedom are interchanged. Problem 2 explores the variances of two samples if F is near 1. They will also find critical values using the Fcdf command on the home screen and then confirm the ...Critical value (z*) for a given confidence level. If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate. More precisely, it's actually 1.96 standard errors.
