Answer:
42.1% of variation in the response is explained by the regression line
Step-by-step explanation:
Correlation coefficient is a measure which tells us that how strongly are two variables under study are linearly related to each other i.e correlation coefficient gives the strength of linear association between the variables.
If the magnitude of correlation coefficient is closer to 1, it indicates a strong linear relationship. If the magnitude of correlation coefficient is closer to 0, it indicates a weak linear relationship.
There is another variable known as "Coefficient of Determination", which is equal to square of Correlation Coefficient. Coefficient of Determination tells us that what percentage of variation in the response of the study can be explained by the regression line.
This means, for this question we need to calculate the Coefficient of Determination.
Correlation coefficient = r = 0.649
Coefficient of Determination = R = r² = (0.649)²= 0.421 = 42.1 %
This means that 42.1% of variation in the response is explained by the regression line.

The probability that a vowel will land face up on the cube would be 1/2. This is because there are six total letters; three vowels and three consonants, so there is a 3/6 chance of it being a vowel and you simplify it down to 1/2. I hope this helped :)
The percentage of price of mangoes was increased by 15% from November to January.
<u>Step-by-step explanation:</u>
- The price of mangoes in November = $12 per kilo
- The price of mangoes in January = $18 per kilo
- The cost has been increased from $12 to $18.
Therefore, the change in percentage is percentage increase.
Percentage increase = (difference between two prices / lower price) × 100
⇒ (18-12 / 12) × 100
⇒ (6 / 12) × 100
⇒ 50 %
Therefore, the percentage change from November to January is increase of 50 %.
Given:
Machine dispenser
Average = 600 mL soda to every glass
Volumes recorded in one day (random sampling)
600.15
599.92
599.85
599.92
599.81
600.14
600.04
599.98
Average = (sum of the volumes)/(number of readings)
= 4799.81/8
Average = 599.976 mL
Therefore there is sufficient evidence to conclude that the average volume of soda dispenser is different from 600 mL.
