Answer:

Mode = 15

Mean = 12.8

Step-by-step explanation:

Given the data :

As obtained form the dot plot :

X : 11, 11, 11, 12, 12, 12, 13, 13, 13, 13, 14, 14, 15, 15

The mean of the data:

Mean = ΣX / n

Mean = 179 / 13

Mean = 12.785 = 12.8 years

Mode = most frequently occurring value = 15

Answer:

Type I error.

Step-by-step explanation:

Let's remember the definition of Type I error and Type II error:

A type I error is the rejection of a true null hypothesis, this means that we would get a "false positive" with this error.

A type II error is the non rejection of a not true null hypothesis, this error would give us a "false negative".

In this problem, we are told that the mean match score to identify a suspect is 80. However, the test shows that the mean match score is more than 80 when the person doesn't have a fingerprint match (and therefore the person would not be a suspect). Therefore, this person would appear as a suspect when he/she really isn't one. This means that the test is giving a "false positive". Thus, this is a type I error.
