Answer:
d) r=0.90
Step-by-step explanation:
When the r value is closer to +1 or -1, it indicates that there is a stronger linear relationship between the two variables. A correlation nearerto -1 is a strong negative correlation while a correlation of 0.10 would be a weak positive correlation.
Correlation coefficient measures the strength of association between two variables.
It may be positive or negative.
If nearer to 1 or - there is strong correlation
Since here is it 0.90 positive and nearer to 1 out of all 4 options
option d is correct
