Exercise 3: Marketing intelligence report

1.   42%, based on 2000 internet users aged 16+

2.   45% of male

       38% of females Based on the 1431 internet users who use social networking sites (assuming the initial          sample of 2000 was evenly divided between men and women, 39+28=67% of the men use social                   networking sites, and 45+30=75% of the women use social networking sites. Therefore the 1431 social        networking site users are divided approximately into 670 men and 750 women)

3.   86%, based on 6.22% of 2000 = 124 social networking site users in the 20-24 age group

4.   As seen above, 67% of men and 75% of women use social networking sites, based on a sample of                 1000 men and 1000 women

       The results are all based on different amounts of data. The results based on larger numbers of people             are the most reliable (questions 1 and 4).

       The results based on smaller numbers of people are least reliable (question 3).
