Decision Theory
Solve the following problem:
The number of sandwiches sold at a shop near a University varies by day of the week. The number of students attending class also varies by day of the week, as the following table indicates. The University will soon include a full Saturday schedule, and it believes 1,500 students will attend those Saturday classes. Using the regression method, forecast the number of sandwiches the shop will sell if it is open on Saturday. Show your work.
Day Sandwiches sold Students attending class
Monday 90 2,000
Tuesday 109 2,400
Wednesday 100 2,100
Thursday 114 2,500
Friday 86 1,700
Saturday ? 1,500
