Answer:

Alpha (α) is used to measure the error for decisions concerning true null hypotheses, while beta (ß) is used to measure error for decisions concerning false null hypotheses.

Step-by-step explanation:

Suppose we have events X and Y.

1. If it is said that X equals Y, when X is actually not equal to Y, α is used in this case, the null hypotheses.

2. If X is said to not be equal to Y, when X is actually equal to Y, β is used in this case, the false null hypotheses.

Step-by-step explanation:

First, you want to add up the subtotal together, so its 5.54+2.49+3.73, and adding those together you get 11.76 as your subtotal. To figure out change, you simply subtract your subtotal to the amount he paid in. For that it is 20-11.76, and that is 8.24

Elliot gets $8.24 in change.
