A paint company claims that the mean time taken for its paint to dry when motor vehicles are repaired is 3.55 hours, with a standard deviation of 0.66 hours.
Assume that the drying time for the paint follows a normal distribution and that the claimed standard deviation value is accurate.

At a car crash repair centre, it was found that the mean time taken for the paint company's paint to dry on randomly selected vehicles was 3.85 hours. The management of this crash repair centre was not happy and believed that the claim regarding the mean time taken for the paint to dry was too low. To test the paint company's claim, a statistical test was carried out.

Each branch within the association pays an annual fee based on the number of members it has.
To encourage each branch to find new members, two new annual fee systems have been proposed.
Proposal 1 is shown in the graph below, where the proposed annual fee per member, in dollars, is displayed for branches with up to 25 members.
Complete the inequality by writing the appropriate symbol and number in the box provided. (1 mark)

Proposal 2 is modelled by the following equation.
annual fee per member = – 0.25 × number of members + 12.25
