To find the inverse of a function, simply switch y with x:
So, y = 5x2 + 10 will become x = 5y2 + 10.
The correct option will therefore be A.
Using error concepts, it is found that in this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.
<h3>What are Type I and Type II errors?</h3>
- Type I: Rejection of a true null hypothesis. The null hypothesis is true, but from a sample, you get enough evidence to reject.
- Type II: Non-rejection of a false null hypothesis. The null hypothesis is false, but from a sample, you do not get enough evidence to reject.
Hence:
In this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.
