Question

Suppose that Ho:us0.01 Ha:H> 0.01 The value 0.01 is the maximum safe level of some naturally occurring lethal pollutant in drinking water for human consumption. You need to decide if you will use water coming from a specific source for one of the beverages your company produces, based on sample measures of this pollutant taken in random different locations and times at the source of water. In this case you would want to O maximize the power of the test O maximize O minimize O maximize th O maximize 1-a

Explanation / Answer

Type I and type II errors. ... In statistical hypothesis testing, a type I error is the incorrect rejection of a true null hypothesis (also known as a "false positive" finding), while a type II error is incorrectly retaining a false null hypothesis (also known as a "false negative" finding). Hence,

We have to minimize Beta here

But

Power = 1 - Beta

So, if beta is minimized, power will be maximized
