Aplumber is trying to fix a clog in a vertical pipe, but does not know how far down in the pipe the clog and the water level is. he is a good whistler, so he whistles into the open end of the pipe and finds that a frequency of 197hz (cycles per second) returns a loud resonant sound. he knows the speed of sound is 340 m/s. calculate the depth of the air in the pipe (in meters) above the clog.

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
