The approximate Z-score that corresponds to a right tail area of 0.20 is
(Round to two decimal places as needed.)

To find the Z-score corresponding to an area of 0.20 to the right, you can look up the value in a Z-table. Since the Z-table typically provides the area to the left of the Z-score, you’ll need to subtract 0.20 from 1, giving you an area of 0.80 to the left. Upon consulting the Z-table, you’ll find that the Z-score that corresponds to an area of 0.80 is approximately 0.84. Thus, the Z-score is about 0.84 when rounded to two decimal places.

To ensure accuracy when looking up values, remember that Z-tables can differ slightly by design, so it’s always a good idea to double-check your Z-score calculations with a reliable source or even a calculator that provides Z-scores and tail areas directly. This way, you can avoid any potential discrepancies!
