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.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
