Question 2

Answer 1

The completed statements with regards to the directors study are;

• For the Midwest region the average number of sales orders per representative for the group that had training is 0.19 more than the average number of sales per representative for the group that had no training.

• For the Northeast region the average number of sales orders per representative for the group that had training is 0.37 more than the average number of sales per representative for the group that had no training.

• The data from the sales director's study indicate that the one-month training program improves sales.

How can the correct options be obtained?

The number of sales representative = 200

For the Midwest region, we have;

$average(t)= \frac{234}{200} = 1.17$

$average \: (non)= \frac{196}{200} = 0.98$

The difference between the averages is therefore;

∆x = 1.17 - 0.98 = 0.19

For the Northeast region, we have;

$average \: (t) = \frac{252}{200} = 1.26$

$average \: (non) = \frac{178}{200} = 0.89$

∆x = 1.26 - 0.89 = 0.37

The sales by the sales representative that had the one-month training is higher than those that did not have training
