Question

2. We are testing to see if a new drug is more effective in treating high blood pressure than the most commonly used drug. The drug used most often is known to control blood pressure in 75% of patients using it. The null hypothesis is that the new drug will control blood pressure in 75% of patients using it (the same as the most commonly used drug). The alternative hypothesis is that the new drug will control blood pressure in more than 75% of patients using it. We would make a Type 2 Error if: A) We conclude that the new drug controls blood pressure in 75% of patients using it when actually the new drug controls blood pressure in more than 75% of patients using it. B) We conclude that the new drug controls blood pressure in 75% of patients using it when actually the new drug controls blood pressure in 75% of patients using it. C) We conclude that the new drug controls blood pressure in more than 75% of patients using it when actually the new drug controls blood pressure in more than 75% of the patients using it D) We conclude that the new drug controls blood pressure in more than 75% of the patients using it when actually the new drug controls blood pressure in 75% of patients using it.

Explanation / Answer

Type 2 Error: Accepting H0 when H0 is false.

Ans: A) We conclude that the new drug controls blood pressure in 75% of patients using it when actually the new drug controls blood pressure in more than 75% of patients using it.
