Before making a complete switch from BlackBoard to Canvas, the usage rate of BlackBoard was

reported to be 56.43% in a recent month. Suppose that you decide to select a sample of 100

students at your university and you find that 60 use the BlackBoard platform.

(a) Use the critical value

approach to determine whether there is evidence that the usage rate

for the BlackBoard platform at your university is greater than the reported usage rate of

56.43%. (Use the 0.05 level of significance.)

(b) Suppose that the sample is n = 600, and you find that 60% of the sample of students at your

university (360 out of 600) use the BlackBoard platform. Use the

p-value

approach to try to

determine whether there is evidence that the usage rate for the BlackBoard platform at

your university is greater than the reported usage rate of 56.43%. (Use the 0.05 level of

significance)
