I only need B1-5

Recent research commissioned by Vodafone suggests that older workers are the happiest employees (BBC News, July 21, 2008). The report documents that 70% of older workers in England feel fulfilled, compared with just 50% of younger workers. A demographer believes that an identical pattern does not exist in Asia. A survey of 120 older workers in Asia finds that 75 feel fulfilled. A similar survey finds that 58% of 210 younger workers feel fulfilled.(You may find it useful to reference the appropriate table:
z tableor t table)

At the 5% level of significance, test if older workers in Asia feel less fulfilled than their British counterparts.

a-5.What is the conclusion?

multiple choice 3

• 
  
  
  

  Older workers in Asia feel less fulfilled

At the 5% level of significance, test if younger workers in Asia feel more fulfilled than their British counterparts.
