When we have negative exponents, we can move the term with the exponent to the bottom of the fraction. This is also known as multiplying by the reciprocal (and changing the negative exponent to be positive!).

The reciprocal of z^-3 would be 1 / z^3.

Hope this helps!! :)

Suppose a sales manager wants to compare different sales promotions. He chooses 5 different promotions and samples 10 random sto

elixir [45]

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:

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

Thus, the correct p-value is 0.106.
