The weights of coffee in 70 jars is shown in the following table Determin variance and standard deviation of the above distribution |
Answer» ![]() `thereforesigma^(2)=(Sigmaf_(i)d_(i)^(2))/(Sigmaf_(i))-((Sigmaf_(i)d_(i))/(Sigmaf_(i)))^(2)=(102)/(70)-((-38)/(70))^(2)` Now =1.4571-02916=1.1655 `sigma=sqrt(1.1655)=1.08g` |
