Please answer these (3) questions 

In 2017, Credit Samouel, a globally operated bank underwent a  massive re-branding campaign.  During this campaign, the bank's product  range was also restructured, and its service and customer orientation  improved.  In addition, a comprehensive marketing campaign was  launched.  It was aimed at increasing the bank's customer base by one  million new customers by 2025.

To control the campaign's success and to align the marketing  actions, management decided to conduct an analysis of newly acquired  customers.  Specifically, management is interested in evaluating the  segment of customers aged 30 and below.  To do so, the marketing  department surveyed the following characteristics of 251 randomly drawn  new customers (variable names in parentheses):

* Gender (gender: male/female)

* Bank deposit in Euro (deposit: ranges from e0 to e1,000,000)

* Is the customer currently enrolled in a college or university (training: yes/no)

* Customer's age specified in three categories (age_cat: 16-20, 21-25, and 26-30)

Use the data in "bank.dta" (attached) to answer the following questions:

1) Which test do we apply to find out whether there is a significant difference in bank deposits b/w male and female customers?  Do we meet the assumptions required to conduct this test?  Carry out an appropriate test to answer the initial research question.

2) Is there a significant difference in bank deposits b/w customers who are still studying and those who are not?

3) Which type of test would you use to evaluate whether bank deposits differ significantly b/w the three age categories?  Carry out this test and interpret the results.
