Garret studies number of hours sleep per night among students who have a grade point average of 3.0–4.0 versus students who have a grade point average of 2.0–3.0.
His theory is that students who get more sleep will have a higher grade point average than students who get less sleep because they are more rested and, therefore, better able to concentrate.
In his samples, the mean number of hours of sleep students with a grade point average of 3.0–4.0 received each night was 6.8. The mean number of hours of sleep students with a grade point average of 2.0–3.0 received each night was 6.4.
Assuming there are no outliers or skew, do the results support Garret's theory?
Select from the drop-down menus to correctly complete the statements.

Give the person above me brainlyest for helping!
Step-by-step explanation:
The coefficient of correlation for the given data of x and y is 0.78.
x and y have a strong, positive correlation
What is Coefficient of Correlation?
A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.
Here, given values of x and y
x 1 2 3 4 5 6
y 3 4 9 7 2 18
xy 3 8 27 28 10 108
x² 1 4 9 16 25 36
y² 9 16 81 49 4 324
∑x = 21, ∑y = 43, ∑xy = 194, ∑x² = 91, ∑y² = 483, n = 6
Now, Correlation between x and y
r = (n∑xy - ∑x.∑y)/ √[{n∑x²- (∑x)²}{n∑y² - (∑y)²}]
r = ( 6 X 194 - 21 X 43 ) / √[ {6 X 91 - (21)²}{ 6 X 483 - (43)²}]
r = ( 1164 - 903) / √( 546 - 441)(2898 - 1849)
r = 261 / √ 105 X 1049
r = 261 / √110145
r = 261 / 331.88
r = 0.78
Thus, The coefficient of correlation for the given data of x and y is 0.78.
x and y have a strong, positive correlation

Think of the decimals in the probability column as percentage. So Micheal has a 30% chance of eating the next fry, Lidia would have a 10% chance, so on and so forth.
The percentage will always go up to 100%.
You're given the other people's percentages, but not Ronald.
So in order to find out the answer, add all of the people's numbers, and subtract by one.

Angel decides to exceed the walking challenge goal. Describe two ways you might adjust the equation or inequality in Part A to represent Angel’s decision to exceed the goal. Give an example and explain.
Answer:
Step-by-step explanation:
The original distance that Angel wanted to walk will be represented as A
Since we don't know the additional distance Angel walked it'll be represented as B
A= the amount of distance Angel wanted to walk
B= the amount of distance Angel wanted to walk past his/her challenge goal
C= the amount of distance Angel walked originally from to past her/his challenge goal
A+B=C
Example:
I decide to work for A hours today as a challenge. Within this time I'm working I decided to extend my goal another B hours.
