1. What is Quantile, Which function is used to find the Quantile? Explain its parameters using full programming Example.

2. Find the output of the following Command:
```df=pd.DataFrame({'Qty1':[20,30,40],'Qty2':[80,85,82]})
print(df.var()['Qty1'])
```
3. For the given code fill in the blanks so that we get the desired output with maximum value for Quantity and Average Value for Cost:
```import pandas as pd
import numpy as np
d = {'Product':['Apple','Pear','Banana','Grapes'],
'Quantity':[100,150,200,250],
'Cost':[1000,1500,1200,900]}
df = pd.DataFrame(d)
df1 =_________________________________
print(df1)

Quantity      250.0
Cost          1150.0
dtype:     float64
```

4. Write a Program in python to find 0.75 quantile of series[1, 10,20,40,60,70,80,90,100].
5. A dataframe df1 stores data about passengers, flight and years as below:
Year Month Passengers
0 2009 January 112
1 2009 February 118
2 2009 March 132
3 2009 April 129
4 2009 May 121
1. Compute total passenger per year.
2. Compute average passengers per month.
6. Explain use of std() and mad() with example.
7. Consider data frame as shown below.
