A) A health care professional wants to determine whether individuals with hypertension who take Atenolol have significantly lower systolic blood pressure than individuals with hypertension who do not take Atenolol. For individuals who have not been prescribed Atenolol, the population systolic blood pressure mean is 165 (µ = 165). The sample of 30 individuals who take Atenolol have an average (mean) systolic blood pressure of 147, with a sample standard deviation of 6. On the basis of these data, can the researcher conclude that the Atenolol significantly lowers systolic blood pressure?

The most appropriate alternative hypothesis (in symbols) would be:

µ_{BloodPressure} = 165

µ_{BloodPressure} = 147

µ_{BloodPressure} < 165

µ_{Blood pressure} < 147

B) A health care professional wants to determine whether individuals with hypertension who take Atenolol have significantly lower systolic blood pressure than individuals with hypertension who do not take Atenolol. For individuals who have not been prescribed Atenolol, the population systolic blood pressure mean is 165 (µ = 165). The sample of 30 individuals who take Atenolol have an average (mean) systolic blood pressure of 147, with a sample standard deviation of 6. On the basis of these data, can the researcher conclude that the Atenolol significantly lowers systolic blood pressure? Set alpha equal to .01.

Set up the criteria for making a decision. That is, find the critical value using an alpha = .01. (Make sure you are sign specific: + ; - ; or +/-) (Use your tables)

C) A health care professional wants to determine whether individuals with hypertension who take Atenolol have significantly lower systolic blood pressure than individuals with hypertension who do not take Atenolol. For individuals who have not been prescribed Atenolol, the population systolic blood pressure mean is 165 (µ = 165). The 241 individuals who take Atenolol have an average systolic blood pressure of 147, with a sample standard deviation of 15.4. On the basis of these data, can the researcher conclude that the Atenolol significantly lowers systolic blood pressure? 

What is the numeric value of your standard error?

D) A health care professional wants to determine whether individuals with hypertension who take Atenolol have significantly lower systolic blood pressure than individuals with hypertension who do not take Atenolol. For individuals who have not been prescribed Atenolol, the population systolic blood pressure mean is 151 (µ = 151). The 34 individuals who take Atenolol have an average systolic blood pressure of 147, with a sample standard deviation of 25. On the basis of these data, can the researcher conclude that the Atenolol significantly lowers systolic blood pressure? 

What is the z-value or t-value you obtained (your test statistic)? (numeric value only, including negative sign if required)

E) A health care professional wants to determine whether individuals with hypertension who take Atenolol have significantly lower systolic blood pressure than individuals with hypertension who do not take Atenolol. For individuals who have not been prescribed Atenolol, the population systolic blood pressure mean is 165 (µ = 165). The sample of 30 individuals who take Atenolol have an average (mean) systolic blood pressure of 147, with a sample standard deviation of 6. On the basis of these data, can the researcher conclude that the Atenolol significantly lowers systolic blood pressure? Set alpha equal to .01.

Suppose that the value of your calculated (obtained) test statistic is -16.51. What is your decision?
