CAN SOMEONE please use SPSS and do STEP by STEP???
An investigator predicts that individuals that fit the Type A
Behavior Pattern (highly competitive and time conscious) will have
higher scores on a questionnaire measure of need for achievement
than individuals that fit the Type B Behavior pattern (absence of
Type qualities). The investigator collects need for achievement
scores from 10 Type A subjects and 10 Type B subjects. Higher
scores reflect greater levels of need for achievement.

An investigator analyzed the leading digits from
792
checks issued by seven suspect companies. The frequencies were
found to be 44,13,55,71,483,175,55,19 and 17,
and those digits correspond to the leading digits of 1, 2, 3,
4, 5, 6, 7, 8, and 9, respectively. If the observed frequencies
are substantially different from the frequencies expected with
Benford's law shown below, the check amounts appear to result from
fraud. Use a
0.025
significance level to test for goodness-of-fit withBenford's
law. Does it...
