A survey of 300 union members in New York State reveals that 112 favor Republican candidate of governor. Construct the 98% confidence interval for the true population proportion of all New York State union members who favor the Republican candidate.

p-hat = 112/300 = 0.37
--------
ME = 2.3263*sqrt[0.37*0.63/300] = 0.0648
===================
98% CI:: 0.37-0.06 < p < 0.37+0.06
=======================
Cheers,
