One way is to square both numbers. You get 9 and 16. 
All the whole numbers between those is 10, 11, 12, 13, 14, and 15. 
The square root of each of those numbers will be irrational and between 3 & 4. 
Hope this helps!

In a study published on January 31, 2011 in The Proceedings of the National Academy of Sciences, researchers randomly assigned 1
Kaylis [27]

Answer:

d.

Step-by-step explanation:

Hello!

The objective of this test is to know if aerobic exercise modifies hippocampus activity. A random sample of 120 elderly men and women was taken and divided into two groups.

Group 1: Walked around a track three times a week.

Group 2: Did a variety of less aerobic exercises, including yoga and resistance training with bands.

After a year their brains were scanned showing that group 1 had an increase of 2% in their hippocampus and group 2 showed a decrease of 1.4%

a. True, this type of observational study can be the prelude to a more formal statistical study.

b. True, the explanatory variable is "type of exercise", it's the variable that the investigator suspects influence the hippocampus volume.

c. True, the objective of this experiment is to test if there is any modification on hippocampus volume, that's why the volume of the hippocampus was measured, before and after a year of exercise.

d. False, this is an observational study, you cannot establish a causal relationship between the two variables. Just inform you that there seems to be an association. To be able to generalize the results to all elderly population you need a more formal statistical experiment to support your conclusions.

I hope it helps!

624 feet to 702 feet state whether the percent of the change is an increase or decrease
Ghella [55]

Answer:

The percent of change is an increase.

Step-by-step explanation:

624 has been changed to 702.

Percent change = [(Value after - Value before ) / Value before]*100

                          =\frac{702-624}{624}*100

                          =\frac{78}{624}*100

So we can clearly see that percentage change is a positive change. This means that the Value after change is higher than value before the change. So the percent of change is an increase.
