Executive Summary
The aim of the report is to highlight the results obtained by the statistical analysis of the data
provided with regards to movie downloads from an internet site. From the population data, a
random sample of 50 consumers has been drawn. Using numerical and graphical techniques, a
summary of the various variables of the sample data has been presented. Further, 95%
confidence interval has been estimated for the purchases of Sci-Fi movie as the first choice and
also the average dollar amount spent. These are then compared with actual population means.
Also, hypothesis test has been used to test the claim whether the average spend on comedy as
first choice exceeds that of drama. This claim is not supported by the sample data. Also, the other
claim regarding purchase being gender dependent also lacked supported from sample data.
Besides, age of customer is not a significant variable influencing the dollar amount spent by the
customers as determined from correlation and regression analysis.
