1 B
2 A
3 B
Explanation:
1
The population is the total sample from which part of the event is considered. It's like in a set, the population would encompass everything as a whole. From the statement given, we're expected to find the population. The population is B.
All NBA players since 1966. This is because it is from this pool that the draft picks were selected, and narrowed down to 45% which were centre backs.
2
The specified attribute is A.
Being a No. 1 draft pick, because that's the fulcrum of the statement in itself
3
B sample proportion. The population like I stated above, is all NBA players since 1966, thus, a population proportion would have had the statement like this.

So, therefore, it's a sample proportion since it is referring to the draft pick, and not the NBA players
