Answer:

0.9 grams

Step-by-step explanation:

The point estimate for the average weight of Soap Bar A is:

A=\frac{121+122+124+ 123+ 120+ 124+ 121+ 121+ 121+ 123+ 120}{11}\\A=121.82\ grams

The point estimate for the average weight of Soap Bar B is:

B=\frac{121+120+122+ 119+ 121+ 122+ 122+ 120+ 120 +121+ 122+123+119}{13}\\B=120.92\ grams

Therefore, the point estimate for the true difference between the given population means is:

Dif = A-B\\Dif = 121.82-120.92\\Dif=0.9\ grams

The point estimate for the difference is 0.9 grams.

radius = 9/2= 4.5

Area of circle = 22/7 × radius²

so,

22/7×4.5×4.5 = 63.6428571

if we round off it to nearest tenth it will be = 63.6
