PROBLEM 11E

The Biomechanics Lab at Hope College tested healthy old women and healthy young women to discover whether or not lower extremity response time to a stimulus is a function of age. Let X and Y respectively equal the independent response times for these two groups when taking steps in the anterior direction. Find a one-sided 95% confidence interval that is a lower bound for μX−μY if n = 60 observations of X yielded

and sx = 129,while m = 60 observations of Y yielded

and sy = 93.

Step-by-Step Solution:
Step 1 of 3
