Discrete Mathematics’ professors at AUA have calculated that in the past the fail rate of the course was 32%. They claim that this year the fail rate has changed. If in a sample of 120 students, 25 have failed the course, what can you conclude about their claim? Use alpha=0.05. Select one:

a.
The p-value is 0.008, which is less than 0.05, therefore, we reject the null hypothesis

b.
The p-value is 0.004, which is less than 0.01, therefore, we reject the null hypothesis

c.
The p-value is 0.008, which is less than 0.05, therefore, we fail to reject the null hypothesis

d.
The p-value is 0.004, which is less than 0.05, therefore, we reject the null hypothesis
