Task 4

The scope of the task is to test the belief that there is no significant difference of the average ages of the buyers of three different luxury cars

Type of cars is taken on the horizontal axis which is analysed with average age of buyers on vertical axis.

Bar chart will created by using excel with help of the given data. 

The people of average age 45.21538462 have bought BMW.

The people of average age 50.45714286 have bought LEXUS. 

The People of average age 51.98666667 have bought Mercedes.

This means that Mercedes is attracted by more aged people. This decision is made clear that there is considerable difference in age for buying cars.

Task 5

In this task we will discuss about the belief that that there is no significant difference in mean household incomes of the three different luxury cars.

Type of cars is taken on the horizontal axis which is analysed with average annual income of buyers on vertical axis.

Bar chart is created by using excel with help of the given data. 

People of An average annual income 139271.3385 dollar have bought BMW. 

People of An average of annual income 154186.8571 dollar have bought LEXUS. 

People of An Average of annual income 184423.9467 dollar have bought Mercedes.

This makes us feel Mercedes as the choice of most annual income. This decision is made clear that there is a substantial amount of annual income on buying cars

Task 6

In this task we will discuss about the belief that that there is no significant difference in mean household incomes of the three different luxury cars.

Type of cars are taken on the horizontal axis which is analysed with Average of Education (Years) of buyers on vertical axis.

Bar chart will created by using excel with help of the given data. 

People of An Average of Education (Years) 15.83076923 have bought BMW. 

People of An Average of Education (Years) 15.8 have bought LEXUS. 

People of An Average of Education (Years) 17.29333333 have bought Mercedes.

This makes us feel Mercedes as the choice of higher education (year) people. This decision is made clear by considering a substantial amount of years of education in buying luxury cars.

Task 7

In this task we will discuss about the belief “Some other car dealers claim that older people with higher household income and more years of education prefer Mercedes to BMW or Lexus”.

Above table contains type of cars with respect to age, average annual income, and average education details of the buyers

It will clearly show when the ages of buyers’ increases BMW car lose their place. It means that people with higher age and higher annual income people do not prefer BMW.

Our problem is some other car dealer’s claim that older people with higher household income and more years of education prefer Mercedes to BMW or Lexus. It may be false because highest education of people with low level income also selecting Lexus.

For example ,in this table take that 70 aged customer their annual income is 184735 dollar  but their years of education is low when compared with others they choose Mercedes as favourite car.

May be annual income of the customer and age will affect the choosing of their favourite car but year of education doesn’t matter when choose a favourite car.
