QUESTION 10The purpose of this study is to see the relation between the percent of body fat with various body circumference measurements. Percentage of body fat for an individual can be estimated once body density has been determined. Folks (e.g. Siri (1956)) assume that the body consists of two components - lean body tissue and fat tissue. The 40 data of percent body fat from Siri's (1956) equation and weight (lbs) are shown below.
The hypothesis is rejected because F ₀ = 7.8421 is bigger than 4.08
10 (e)
Intercept = Slope =
From the regression line, the value of intercept is fixed and the vlue of slope can be changed whether increase or decrease depends on value of x. When weight (lbs), x is increased then the percent of body fat, y is also increase.

STEP 1:
State the hypothesis
(two tail test)
STEP 2:
STEP 3:
10 (f)
STEP 4:
Accept H0, since Ztest is more than Ztable.

So,Coefficient of Pearson is below 0.5, so it is weak positive correlation.
