Answer:
a) It is a one-tailed test
Step-by-step explanation:
The number of plants he sets up in the room, n = 20
The number of plants that grew more with Miracle Grow = 14
The alpha level α = 0.01
A one-tailed test is used when the critical-area of interest in the distribution is either to the left or right of a value on the number line. That is the test is concerned if the test result is either less than or more than a value
In the test the farmer subjects all 20 plants to the same test treatment without any control experiment, therefore, the farmer evaluates the plants based on how much they grow compared to each other, that is if they grow more or less than their pairs
Therefore a one-tailed test should be used.
Firstly, you have to calculate the 25 percent of the 32 apples which is 32 x 0.25 = 8. So the leftover apples would be 32 - 8 = 24. Since she divided the rest equally among 6 pies, you have to divide 24 by 6, which is 4.
Therefore there are 4 apples in each pie.
