If the alcohol content increases by 1%, the number of calories increases by [ Select ] If there were no alcohol in the beer, the calories would be [ Select ] This correlation is [ Select ] and [ Select ]
1) 83.437513%of variation in calories determined by alcohol content
2) if alcohol content is increased by 1%, the number of calories will increase by 26.318608 in 12 oz
3) if there is no alcohol content, then number of calories will be =25.031236
4) The options are not available and hence, it is not clear. But, the interpretation is the following
This correlation is strong and positive
Step-by-step explanation
The percentage of variation in calories determined by alcohol content is the value of R-squared.
From the given information, R-squared =0.83437513
So, 0.83437513=83.437513%
Therefore,
1) 83.437513%of variation in calories determined by alcohol content
2) The regression line is given to be
Calories in 12 oz =25.031236+26.318608 Alcohol content ( in % )
Now, if alcohol content is increased by 1%, we would get
[ because alcohol content is in %, so, for 1 % increase, we need to add +1 to the "Alcohol content " variable ]
?New Calories in 12 oz =25.031236+26.318608 ( Alcohol content + 1 )
?New Calories in 12 oz =25.031236+26.318608 ( Alcohol content )+26.318608
?New Calories in 12 oz =Previous calories in 12 oz+26.318608
So, For 1% increase in alcohol content, there is a increase of 26.318608 calories in 12 oz
Hence, if alcohol content is increased by 1%, the number of calories will increase by 26.318608 in 12 oz
3) if there is no alcohol content, then number of calories will be
Calories in 12 oz =25.031236+26.318608 (0%)
?Calories in 12 oz =25.031236+26.318608 (0)
?Calories in 12 oz =25.031236
Hence, if there is no alcohol content, then number of calories will be =25.031236
4) The correlation coefficient value is 0.91344136 which is close to +1.
So, this correlation is positive and they are strongly related.
The options are not available and hence, it is not clear as to which is which.
But, this interpretation from the correlation value is that
This correlation is strong and positive
