Expert Solution
Step 1

Given data:

A sample of current BBA members is taken, n = 1250

Number of BBA members who are in favor of merger proposal, x = 962.

Degree of confidence, c = 99%

Level of significance is:

α=1-c=1-0.99=0.01

Let p be the true proportion of BBA members of the population.

Let p^ be the estimated proportion of BBA members.
