7. Two groups of subjects were divided in an experimental study. One group was given a drug to help speed up their metabolism and result in weight loss. The other group was given a placebo (a pill that looks identical

to the one given to the other group, but without the weight loss drug). After a month of the experiment, the

weight loss of each individual in each of the two groups were measured. In general, people in the group who

took the metabolism drug did lose more weight, although there were differences in the amount each lost.

There are two main types of variability occurring in this study. Describe each type below in the context of

this study

Induced Variability

Natural Variability

By definition ( scientific dictionary )

Induced Variability :This type of variability is in marked contrast to natural. It occurs because we have assigned our population or sample to two or more treatment groups and then observe the variability between the groups The results are manipulated by outside factors controlled by the one experimenting.can be controlled

Natural Variability :Variability that accounts for the fact that members of a populations are simply different, Naturally everything is different even in te smallest tings.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
