Find at least three web sites that you can understand about "Hypothesis Testing of Means" or "Hypothesis Testing for Means." One can be StatTrek.com, if you want.
Summarize the concept in a 1-2 page, individually written, discussion of why and how we do hypothesis testing of a mean.
Refrigerant 134a enters the condenser of a residential heat pump at 800 kPa and 35 degrees celcius at a rate of 0.018 kg/s and leaves at 800 kPa as a saturated liquid. If the compressor consumes 1.2 kW of power, determine a) the COP of the heat pump ..
