Best Answer

we know that

The correlation coefficient is a number between [tex]-1[/tex] and [tex]+1[/tex] that represent the linear dependence of two variables or sets of data

Using the function CORREL in a excel tool, calculate the correlation coefficient (r)

see the attached table

the correlation coefficient for the data in the table is equal to [tex]1[/tex]

therefore

the answer is

[tex]r=1[/tex]

A teacher is choosing between two options for a class field trip to an orchard.
  • At Orchard A, admission costs $ 9 $9 per person and 3 chaperones are required.
  • At Orchard B, the cost is $ 10 $10 per person, but only 1 chaperone is required.
  • At each orchard, the same price applies to both chaperones and students.
    Which orchard would be cheaper to visit if the class has 8 students?
    Orchard B
    Both orchards since they cost the same price.
    Orchard A
    Neither orchards because both cost too much.
