Question

Part 2 Part 3 464 patients in a local clinic participated in a study to examine whether Direct HDL Cholesterol (mg/dL) explains variation in Total Cholesterol mg/d). Here is some output obtained when a bivariate regression analysis was performed o Summary ANOVA Coefficient Dependendolo Accepted characters: Only numbers, decimal point markers e, periods or sign indicators preceding a number leg.-5) are allowed except where scientific notation is needed.

Se 3 means 3x10-3L change for at How many standard deviations does Total Cholesterolimgid standard deviation change in Direct HDL-cholesterol mg du?

Answer 1

Answer: Yes

Explanation:

	F	Significance
Regression	7.804	0.005

The significance F value is 0.005 which is less than 0.05 at a 5% significance level which means the model significantly fits the data value at a 5% significance level compared to the model with no independent variable.

Answer: 0.129

Explanation: The standardized coefficient estimate for the independent variable Direct HDL-Cholesterol is 0.129 which means for one standard deviation change in the independent variable, the dependent variable changes by 0.129 standard deviation.
