Solution Summary

The expert locates a z score for 1.645 associated with an alpha of 0.05. A complete, neat and step-by-step solution is provided.

Solution Preview

(1) For a t- score of 1.645, the probability value depends upon the degrees of freedom, which in turn depends upon the

sample size (n). Please clarify what is the sample size.
