    Andrea is the manager of a company which makes mobile phone chargers.
    In the past, she had found that \(12 \%\) of all chargers are faulty.
    Andrea decides to move the manufacture of chargers to a different factory.
    Andrea tests 60 of the new chargers and finds that 4 chargers are faulty.
    Investigate, at the \(10 \%\) level of significance, whether the proportion of faulty chargers has reduced.

14 A retail company has 5200 employees in 100 stores throughout the United Kingdom. The company recently introduced a new reward scheme for its staff.
The management team wanted to sample the staff to find out their opinions of the new scheme. Three possible sampling methods were suggested:
Method A Choose 100 people who work at the largest store
Method B Choose one person at random from each of the 100 stores
Method C List all employees in alphabetical order and assign each a number from 1 to 5200 Choose a random number between 1 and 52
Choose this person and every 52nd person on the list thereafter. 14
  1. Give one disadvantage of using Method A compared with using Method B.

19 It is known from historical data that 15\% of the residents of a town buy the local weekly newspaper, 'Local News'. A new free weekly paper is introduced into the town.
The owners of 'Local News' are interested to know whether the introduction of the free newspaper has changed the proportion of residents who buy their paper. In a random sample of 50 residents of the town taken after the free newspaper was introduced, it was found that 3 of them purchased 'Local News' regularly. Investigate, at the \(5 \%\) significance level, whether this sample provides evidence that the proportion of local residents who buy 'Local News' has changed.
