Question

22.

A study reports that administering vanocmycin incorrectly is not associated with red man syndrome. You know this means: select only one answer.

		a. The p value was greater than alpha
		b. The null hypothesis was rejected
		c. A type I error was made in administering the medication
		d. The p value was less than alpha

25. You are reading a study that examines the impact of alcohol use, oestradiol use, and obesity on liver disease. It reports the following beta coefficients for the regression equation.

Alcohol use  (b₁= 3.45)

Oestradiol use (b₂= -0.98)

Obesity (b₃= 1.67)

Assuming all three variables are significant predictors of liver disease, as Oestradiol use increases you would expect to see liver disease:

		a. Decrease
		b. unable to determine
		c. increase
		d. stay the same

Answer 1

(22)

Correct option:

a        The p value was greater than alpha

Explanation:

H0: Null Hypothesis: administering vanocmycin incorrectly is not associated with red man syndrome.

HA: Alternative Hypothesis: administering vanocmycin incorrectly is associated with red man syndrome.

Since the conclusion is: Fail to reject null hypothesis, the p value was greater than alpha

(23)

Correct option:

a. Decrease

Explanation:
Since the sign of the slope coefficient for Oestradiol use is negative, we conclude that as Oestradiol use increases you would expect to see liver disease decrease.
