# Customer Service Requests Analysis
**Project 1**

**_DESCRIPTION_**

## Background of Problem Statement :

NYC 311's mission is to provide the public with quick and easy access to all New York City government services and information while offering the best customer service. Each day, NYC311 receives thousands of requests related to several hundred types of non-emergency services, including noise complaints, plumbing issues, and illegally parked cars. These requests are received by NYC311 and forwarded to the relevant agencies such as the police, buildings, or transportation. The agency responds to the request, addresses it, and then closes it.

## Problem Objective :

Perform a service request data analysis of New York City 311 calls. You will focus on the data wrangling techniques to understand the pattern in the data and also visualize the major complaint types.
Domain: Customer Service

## Analysis Tasks to be performed: 
#### _(Perform a service request data analysis of New York City 311 calls)_

1. Import a 311 NYC service request.
   2. Read or convert the columns "**Created Date**" and "**Closed Date**" to datetime datatype 
      and create a new column "**Request_Closing_Time**" as the time elapsed between request creation 
      and request closing. (Hint: Explore the package/module datetime)
   3. Provide major insights/patterns that you can offer in a visual format (graphs or tables)
      at least 4 major conclusions that you can come up with after generic data mining.
   4. Order the complaint types based on the average "**Request_Closing_Time**", grouping them 
      for different locations.
   5. Perform a statistical test for the following:
      Please note: For the below statements you need to state the Null and Alternate and then 
      provide a statistical test to accept or reject the Null Hypothesis along with 
      the corresponding "**p-value**".

- Whether the average response time across complaint types is similar or not (overall)
      - Are the type of complaint or service requested and location related?
