Locate a z score for 1.645 associated with an alpha of .05 using standard normal areas statistical tables. Then, using a Student’s t distribution statistical table, find the 1.645 value.

Explain why the t distribution approaches the z distribution as the sample size gets larger.

(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.

(2) A careful look into the t …

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.
