HELP HELP PLSthe lamp L1 L2 and L3 are identical knowing that the intensity of the current delivered by the generator is I= 320mA CALCULATE THE INTENSITY OF THE CURRENT FOLLOWING THROUGH EACH LAMP

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
