5. the correlation between the number of dogs kept as pets in the u. s. and money
spent on tennis balls is r = 0.93. does the strong correlation between these two
variables suggest that having more dogs kept as pets causes people to spend mor
money on tennis balls? explain.

As the value of r = 0.93 is closest to +1, therefore it shows the strong correlation between the two variable (number of dogs and money spend on tennis balls), which suggests that having more dogs kept as pets causes people to spend more money on tennis balls.

Step-by-step explanation:

Correlation shows the relationship between two or more variable and determine how weakly and strongly they are co-related to each other.

The value of correlation (r) lies between +1 and -1. If the value is nearest to +1 then it shows the positively strong correlation between two variables. If value is closest to - 1, it shows the strong negative correlation.

Since r = 0.93 which is nearest to +1, therefore it shows the strong positive relationship between the two variables which means increase in quantity of one causes to increase in the quantity of other which states that keeping more dogs will lead to increase in money spend on tennis balls.

i think the answer is b
