Step-by-step explanation:
Correlation
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.
Anxiety symptoms and life satisfaction are negatively correlated. As life satisfaction increases the anxiety symptoms decreases.
Thus, a moderate correlation between them can be expressed by a correlation coefficient of -0.5

Step-by-step explanation:
| Red |Green | Brown Total
<span>Smile |0.100 | .300 | .10 0.50</span>
<span>No smile |0.200 | .150 | .15 0.50
Total 0.30 0.45 0.25 1.00
The probability of choosing red candy is 0.10
The probability of choosing no smile candy is 0.50
The probability of choosing red or no smile = 0.10 + 0.50 = 0.60
I did not use 0.30 as the probability of red because it included the no smile candy. It should only be red candy that has a smile.</span>
