Consider a population proportion p=0.55.
a-1. Calculate the expected value and the standard error of /bar (P) with n=27.
Note: Round "expected value" to 2 decimal places and "standard error" to 4 decimal places.

â—» Yes
No
b-1. Calculate the expected value and the standard error of vec(P) with n=32.
Note: Round "expected value" to 2 decimal places and "standard error" to 4 decimal places.
