Criminal investigators use biometric matching for fingerprint recognition, facial recognition, and iris recognition. When matchi
Art [367]

Answer:

It is not a Type I error neither a Type II error.

Step-by-step explanation:

Let \mu be the true mean match score. The null hypothesis is H_{0}: \mu = 80 and the alternative hypothesis is H_{1}: \mu > 80 (upper-tail alternative). When the test shows that the mean match score is more than 80 when actually is equal to 80 a Type I error is made. On the other hand, when the test shows that the mean match score is equal to 80 when actually is more than 80 a type II error is made. Therefore, when the test shows that the mean match score is more than 80 when the person does not actually have a fingerprint match, does not correspond to a Type I error neither to a Type II error.

What is the value of f(3) when f(x) = 4x + 1
valentina_108 [34]

Here is the equation:

f(x)=4x+1

You need to find f(3). To do that, substitute all the x's with 3:

f(x)=4x+1 \rightarrow f(3)=4\times3 + 1

The first thing you need to do is multiply 4 by 3. Multiply:

4 \times 3 = 12

Here is your new equation:

f(3)=12+1

To get your answer, you need to add 12 and 1. Add:

12+1 = 13

That means:

\bf f(3)=13
