Suppose that

h subscript o : mu less or equal than 0.01
h subscript alpha : mu greater than 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

a. maximize the power of the test
b. maximize beta
c. minimize mu
d. maximize the significance, alpha
e. maximize 1 minus alpha
