A) The attachment shows the equation of the best-fit line. It is approximately
.. test average = 89.7 -2.93*(hours playing games)
b) The slope indicates the expected drop in test score for each hour spent playing games
c) The y-intercept is the expected test score if no hours are spent playing games.
d) The correlation coefficient is -0.92, a significant negative correlation. One might expect that hours spent playing games indicates a lack of interest in school subjects or studying, hence a likelihood that test scores will be lower.
e) The equation predicts a test score of about 75 for someone who spends 5 hours a week playing video games.
Here you go. Hope this helps

Now don't get us wrong – not all of these answers raise this excellent question
A ratio shows us the number of times a number contains another number. The proportion of students that are in middle school and chose french fries is 0.14.
<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
Given that the number of students are in middle school and choose french fries is 56, while the total number of students is 400. Therefore, the proportion of students that are in middle school and chose french fries are,
Proportion = (Number of students in middle school who choose french fries) / (Total number of students)
= 56 / 400
= 0.14
Hence, the proportion of students that are in middle school and chose french fries is 0.14.
