Question

Transcribed Image Text:course are normally distributed with a mean of 67
and a standard deviation of 6. Based on the above
information and a Z-table, fill in the blanks in the
6,
table below.
Precision and other notes: (1) Percentiles should
be recorded in percentage form to three decimal
places.
(2) Note that this problem does not use the rough
values of the 68-95-99.7 rule (that is, the empirical
rule); instead you must use more precise Z-
table values for percentiles.
