appropriate for inference about proportions.

B.) None of these answers are correct.

C.) Z-Tables are most appropriate for inference with small sample sizes, T-Tables are most
appropriate for inference with large sample sizes.

D.) Z-Tables are most appropriate for inference about proportions, T-Tables are most
appropriate for inference about means.

E.) Z-Tables are applicable when you have population data, T-Tables are applicable when
you have sample data.

Answer 1

The correct option regarding when each table is appropriate is given by:

E.) Z-Tables are applicable when you have population data, T-Tables are applicable when you have sample data.
