Answer:
Anterograde
Explanation:
Eli was in a serious car accident and fell into a coma for a few days. When he woke up, he was able toremember his childhood, his family, and other personal information about himself. However, he was neveragain able to remember new conversations he just had, nor remember people he just met or even what he justate for his last meal. Eli is MOST likely suffering from anterograde amnesia. This is a condition brought on by trauma to the head, such as a car accident, in Eli's case. This is not life threatening by itself, but you could have other health concerns related to this diagnosis.
Answer:
Explanation:
The <em>correlation coefficient</em> is a measure of the linear association between two variables.
It is a dimensionless value bettween - 1 and +1. Hence, it does not depend on the units that are used to measure the data.
You can see the formula to calculate the correlation coefficient in the attached picture.
There you see that the numerator containts the sum of the differences of the values of the x-variable with its the mean, multiplied by the sum of the differences of the values of the y variable with its mean, while the denominator contains the square root of the product of the squares of the same differences, thus the units are canceled.
In conclusion,<em> If the teacher changes the units of each variable from hours to minutes, the value of the correlation coefficient between minutes studying and minutes spent on the Internet will not change</em>; it will continue being <em>−0.72.</em>
