the null and the alternative hypothesis are computed as :


This is a two tailed test
This is because of the ≠ sign in the alternative hypothesis which signifies that the rejection region in the alternative hypothesis are at the both sides of the hypothesized mean difference .
Decision Rule: at the level of significance ∝ = 0 . 10
The decision rule is to reject the null hypothesis if z < - 1 . 64 and z > 1 . 64

Step-by-step explanation:
Well the formula for finding the volume of rectangular prisms, is length x width x height, so any 3 numbers multiplied by each other that equal 64 could be the measurements. For example, a length of 2 units, height of 2 units and a width of 16 units has a volume of 64 so that could be your answer.
