You will need to do some data analysis and prepare a short-written report. The written part of the report should not exceed a page in length. Remember, Mr. K is the President of the bank, so you will want to ensure that your report is complete and accurate. A copy of the data appears in page 3. The LTG National Bank has offices in several areas of Metro Manila. Mr. K, President and CEO, would like to know the characteristics of his checking account customers. What is the balance of a typical customer? How many other bank services do the checking account customers use? Do the customers use the ATM service and if so how often? What about debit cards? Who uses them, and how often are they used? To better understand the customers, Mr. K asked Miss G, Director of Planning to select a sample of customers and prepare a report. To begin, she has appointed a team from her staff.

Assume that an outside advocacy group had been lobbying the Mayor's office to convert part-time workers into full-time workers throughout 2014. The Controller's office makes its calculations annually. Suppose that the outside advocacy group wanted to know the proportion of city employees (excluding per-event employees) who are full-time employees p in June 2014 to gauge if their lobbying efforts had been effective. Suppose that the group surveyed a random sample of 1000 city employees (excluding per-event employees) in June 2014 and found that 845 were full-time employees and 155 were part-time employees. If the advocacy group planned to use a one-sample z-test for a proportion to test their lobbying eforts, the appropriate null hypothesis would be and the appropriate alternative hypothesis would be
