A saving of 1/4 can be made on the pillows off of their regular price which means that if the price is d, a saving of 1/4 multiplied by d can be made on the pillow.
When d is multiplied by 1/4, the result is:
= d * 1/4
= d/4
Example:
Assuming d = $8, discount would be:
= 8 * 1/4
= 8 / 4
= $2
This proves the equation gives the dollar discount.
That is true because there is a higher likelihood that a significant difference does not exist, so you would stay with the null hypothesis because your alternative hypothesis is not supported.
