Answer:
The Three way mixed ANOVA
Step-by-step explanation:
The Three factor repeated measures ANOVA analysis otherwise referred to as the Three way mixed ANOVA should be used for the analysis.
This is because we are comparing three independent variables in the context.
• People type (statistic lectures and students)
• Imagery type (positive, neutral and negative imagery)
• Repeated measure: Before and After images shown
• Measuring the dependent variable positive arousal as shown in the table attached to the answer.
After going through the table attached you will see that there should be performed a three factor repeated measures ANOVA analysis.
The number of people who voted follows a binomial distribution with probability of having voted

and

subjects, which means the approximating normal distribution should have mean

and standard deviation

.
With the continuity correction, you have
Credit card A
First 3 months:
4.1% / 360 = 0.011% x 30 = 0.34% per month for the first 3 months.
Next 9 months:
18.5% / 360 = 0.051% x 30 = 1.54% per month for the next 9 months.
Credit card B:
First 3 months
3.7% / 360 = 0.010% x 30 = 0.30% per month for the first 3 months
Next 9 months:
18.9% / 360 = 0.0525% x 30 = 1.575% per month for the next 9 months
Credit Card B is the better deal for the first 3 months.
Credit Card A is the better deal for the next 9 months.
