3. A bank will open a new branch in a particular neighborhood if it can be reasonably sure that atleast 10% of the residents will consider banking at the new branch. The bank will use a significancelevel of 0.05 to make its decision. The bank does a survey of residents of this neighborhood andfind that 19 out of 100 people randomly surveyed said they'd consider banking at the new branch.Based on this sample, should the bank open the new branch?Ho:H₁:p=n =X =p===a =Illustrate the rejection region.which one is the claim?Which statistic will you use?

Identify the paired-difference variable. Determine the null and alternative hypotheses. Classify the hypothesis test as two tailed, left tailed, or right tailed. (b) State one possible advantage of using paired samples instead of independent samples
