Suppose a sales manager wants to compare different sales promotions. He chooses 5 different promotions and samples 10 random stores for each different promotion. The F value is 3.4. Using JMP, find the correct p-value.

Answer:

The correct p-value is 0.106.

Step-by-step explanation:

The information provided is as follows:

  • The sales manager chooses 5 different promotions and samples 10 random stores for each different promotion.
  • The F value is 3.4.

The degrees of freedom are:

k - 1 = 5 - 1 = 4

n - k = 10 - 5 = 5

Compute the p-value using Excel as follows:

[tex]p-value=P(F_{(k-1,n-k)}>3.4)\\\\=P(F_{(4,5)}>3.4)\\\\=F.DIST.RT(3.4,4,5)\\\\=0.106[/tex]

Thus, the correct p-value is 0.106.
