Introduction to Business Statistics
Report:
Write a report to be presented to the management detailing your findings. In your report include a comprehensive discussion on the following:
Discuss the nature of variable types used and their measurement scales.
Selection of an appropriate sample from the dataset. (from the Excel data set: Cardio project)
Create a customer profile for each treadmill product line by developing appropriate tables for different variable types (summary tables, frequency distribution tables) and charts (bar charts, pie charts, scatter plots). Interpret every table or chart presented.
Compute descriptive statistics to create customer profile for each treadmill product line.
For each product line determine whether the numerical variables can be approximated by the normal distribution. Discuss.
Create 95% confidence interval estimates to create a customer profile (eg: age, income) for each Cardio treadmill product line.
Team wants to test following hypothesis: Formulate a hypothesis test to test claims on:
A typical customer walks/runs more than 30 miles/ week.
The mean customer age is above 55 years.
The mean customer income is less than $1000 / week
There is a difference between customer age and the products purchased and income and the products purchased. (conduct two sample hypothesis tests)
Develop a simple linear regression model.
Concluding remarks: Major findings
