Answer:
Correct option: Type II error.
Step-by-step explanation:
In statistical hypothesis testing two kind of errors can be committed by the researcher.
- Type I error: The probability of rejecting a null hypothesis when in fact it is true.
- Type II error: The probability of not rejecting a null hypothesis when in fact it is false.
The power of the test is defined as the probability of rejecting a false null hypothesis. It is denoted by <em>β</em>.
Then the probability of Type II error can be defined as:
P (Type II error) = 1 - <em>β</em>.
The power of the test is affected by the significance level<em>.</em>
If the significance level is less than the power is also less.
The significance level is related to the <em>p</em>-value of the test.
So the P(Correct) = 1 - <em>p</em>-value.

Answer:
maximum 5 CDs
Step-by-step explanation:
Let Mitchell can order a maximum of x CDs
It has been given that each CD costs $15.99, and shipping for the entire order is $9.99.
Thus, we have the total cost for x CDs
Now, Mitchell has no more than $100 to spend. It means
Subtract 9.99 to both sides
Divide both sides by 15.99
Hence, Mitchell can order maximum 5 CDs
