Label each error as either systematic or random . You accidentally measure from the 1 cm mark on a ruler instead of zero Everyone in the class measures diameter of the same wheel but gets slightly different numbers . You step on a scale and it says you weigh 1o kg Your calculations expect you to be at room temperature, but the air conditioning breaks and you do your experiment at 95°F ·You always read your ruler at an angle...

Error Propagation What is error propagation? A question in error propagation is that when we take a product of measurements we do what with the uncertainties? Should our uncertainties get bigger or smaller as they propagate through the formulas? Take a square and measure one side. What happens to the uncertainties when you calculate Area? Can this be beneficial when our product contains measurements of different units? The rule is to find the relative uncertainty in a product of measurements...

d. What is the average and standard deviation of these five z-scores? 3. A stress researcher is measuring how fast people hit a red button after a loud noise. He gathers data from 81 people (N -81). His participants' reaction times are normally distributed. The average reaction time was 2.0 seconds, with a standard deviation of 0.2 seconds. Using a standard normal table (Table A-1), answer the following questions (hint: you need to convert raw scores into z-scores). a. What...

The speed of light was measured 2,500 times. The average measurement was 299,774 kilometers per second and the standard deviation in the sample was about 14 kilometers per second. (a) What are the conditions on the measurement process that need to be satisfied so that you can provide an approximate 95% confidence interval for the speed of light based on the above data? (b) Assuming that these conditions are satisfied, report the corresponding confidence interval for the speed of light...
