Learning Goal: I’m working on a data analytics practice test / quiz and need an explanation and answer to help me learn. The problem must be solved
with a complete step-by-step process. For example, complete tables (if
necessary), complete formulas. You can write your answers by hand or
electronically. The answers must be neat and not confusing. Calculations are to
be done to the 4th decimal place. In the case of looking up values in the
z-distribution tables, you can round to the 2nd decimal place to get the value
from the tables. If you finish the answer you can give it to me earlier.. There
is no use of excel.
Requirements: no
