Answer: Type I error

Step-by-step explanation:

A type 1 error is also referred to as the false positive and it is when a true null hypothesis is incorrectly rejected by the researcher.

On the other hand, type II error which is also refered to as the false-negative is when a null hypothesis which is false is failed to be rejected by the researcher but rather accepted.

Based on the information given in the question, since the data leads to the rejection of the null hypothesis such was later found out to be true, then a type I error has occured.

What is the area of this triangle?

amid [387]

We can solve for the 3 triangle sides.
The left side is easy 6.
Second side² = 7² + 4²
Second side² = 49 + 16
Second side = square root (65)
Second side = 8.0622577483 
Third Side² = 7² + 2²
Third Side² = 53
Third Side = 7.2801098893 
When we know 3 sides, we use Heron's formula for calculating area:
Perimeter = 21.3423676376 
Semi-Perimeter = 10.6711838188 
Using Heron's Formula
area = square root (10.6711838188 * 4.6711838188 * 2.6089260705 * 3.3910739295 )
area = square root (441)
area = 21

Yes, it's just that "easy". LOL
