The government believes that 90% of UK households have access to the internet. Many organisations keen on the digitalisation of the UK economy do not believe this to be the case and they believe that the actual true proportion is smaller than 90%. Investigate this by:
a. Constructing a confidence interval that has a high probability of including the true population proportion of internet users. Comment on your findings.
b. Test the government claim by using hypothesis testing. Comment on your findings.
c. The government also believes that there is no digital divide between the north of England (North East and North West combined) and London. This view is challenged by various local governments in the north of England who claim that the proportion of households connected to the internet is lower than in London. Test this hypothesis and report on your findings.
