Which correlation coefficient obtained from modeling advertising and sales data of tutti frutti ice cream expresses the strongest correlation of the data? a. r = .10 b. r = .50 c. r = .75 d. r = .90

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

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
