Question
#1. An airline would like to conduct a marketing study to identify if passenger satisfaction (yes or no) is associated with type of free snack provided (either peanuts, pretzels, or chocolate). Which test would look at this association?
One-sample t-test
Chi-square test
Sidak post-hoc test
d. One-sample Z-test
#2. A chi-square test with p<0.0001 with alpha=0.05 means there is a significant association.
a. True
b. False
#3. A forensic accountant created a 99% confidence interval for average return claimed by pump-and-dump scammers using e-mail spam. The confidence interval was (4.1%, 5.3%), which has the interpretation of:
The forensic accountant is 99% confident that the average return claimed by pump-and-dump scammers from spam emails is between 4.1% and 5.3%.
The average return falls between 4.1% and 5.3% around 99% of the time.
Scammers earn a return 99% of the time, and it's usually the average of 4.1% and 5.3%, which is 4.7%.
4.3% of pump and dump scammers earn 99% of the return, while 1% earn 5.3%.

Explanation / Answer
1)Chi-square test will be used to check association
2)p-value is less than level which implies that the null hypothesis of zero association is not true.Hence option (a) is correct as there is significant association.
3)Option a is correct that there is 99% chance that the average return claimed by pump and dump scammers from scam emails is between 4.1% to 5.3%
