Find the probability of committing a Type II Error
If men having high blood sugar problems are diagnosed with Diabetes, with the mean blood sugar level to be 150 and a standard deviation of 10, and if any individual with blood sugar greater than 125 can be diagnosed with Diabetes, what is the probability of committing a Type II Error?
OPTIONS
- 0.007
- 0.00655
- 0.0062
- 0.0055
ANSWER
0.0062
EXPLANATION
Z = (150-125)/10 = 25/10 = 2.5 Area under 2.5 corresponds to 0.0062. Thus, the probability of a Type II Error, which is ?, is 0.62%.
