b) There’s a 78% chance that 90% of the deliveries are on time.

c) There’s a 22% chance that the sample they drew shows the correct percentage of on-time deliveries

d) There’s a 22% chance that natural sampling variation could produce a sample with an observed proportion of on-time deliveries such as the one they obtained if, in fact, 90% of deliveries are on time.
