Transcribed Image Text:3. A bank will open a new branch in a particular neighborhood if it can be reasonably sure that at
least 10% of the residents will consider banking at the new branch. The bank will use a significance
level of 0.05 to make its decision. The bank does a survey of residents of this neighborhood and
find 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?
