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 **(b _{1}=
3.45)**

Oestradiol use **(b _{2}= -0.98)**

Obesity **(b _{3}= 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.**
