Clunker Motors Inc. is recalling all vehicles from model years 1995-1998 and 2004-2006. A boolean variable named norecall has been declared. Given a variable model Year, write a statement that assigns true to nore-call if the value of model Year does not fall within the two recall ranges and assigns false otherwise. Do not use an if statement in this exercise!

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
