The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A

let me know if you have any questions!!!

san4es73 [151]

Answer: Using Chi-square.

Step-by-step explanation: To check if the provided data show any differences in preference for the two detergents (i.e., two variables), a Chi-square can be deployed, as it is used to test the goodness of fit, and test if two variables are related.

If the value obtained is less than 0.05, it means that there is statistical difference between the preference for the two detergents.

However, if the obtained value is higher than 0.05, it translates that there is no statistical difference between the preference for the two detergents.
