You will perform a Chi-Square test and an
ANOVA test. For each hypothesis test make sure to
report the following steps:
Identify the null hypothesis, Ho, and the alternative
hypothesis, Ha.
Determine whether the hypothesis test is left-tailed,
right-tailed, or two-tailed.
Find the critical value(s) and identify the rejection
region(s).
Find the appropriate standardized test statistic. If convenient,
use technology.
Decide whether to reject or fail to reject the null
hypothesis.
Interpret the decision in the context of the original...

Kuya conducted a study to see if, among smokers, that there is a
significant difference in the sense of smoking urge between
individuals in various levels of administration. To
measure the urge to smoke, the Chronic Habit Obliging Killer
Emphysema (CHOKE) test was used. Type of profession was
categorized to Upper Management, Middle Management, and Lower
Management. The higher the score, the stronger the
urge. Is there a significant difference in their
urge?
