220AL-E1 he uncertainty in an experimental quantity must be reported. Since there are a number of ways to do this we must state the meaning of the uncertainty. A Estimated uncertaint Sometimes we make several measurements that are identical. Eq 1-2 would yield ơx-0, which could lead to the mistaken impression that the uncertainty is zero when in fact the precision of the instrument is less than the random errors. We must estimate the uncertainty, and,...

Answer the number 3 and 4 question
Worksheet 2: Chapters 3 and 8 (Normal Distributions; Sampling) Math 243, Sunmmer '19, Vargas (c) (3.5) What percentage of all MLB players are shorter than your team's shortest player, according to the Normal distribution? What about taller than your team's tallest player? 3. (3.4) Consider the N(73.7,2.3) distribution for the height in the population of all MLB players. (a) From the population, find the intervals of player heights within one standard deviation of...

The "best" result is always associated with the measurement with the smallest uncertainty. Measurement B has half the standard uncertainty of measurement A. Therefor e our 68 % coverage probability is associated with a smaller interval (83.44 g o 83.56 g) for measurement B than measurement A (83.38 g to 83.62 g). In other words we have better knowledge about the value of the measurand from measurement B, since we have the same coveroge probability associated with a norrower interval....

The Ponaxtiruchiranalignim Car Rental Fleet has 10 of these cars in its fleet, acquired from various (i.e., random) sources. The CO emissions follow a normal distribution. a) What is the probability that a randomly selected car from the street has a CO emission greater than 3.1 gm/mi. b) What is the probability that a randomly selected car from the fleet has...
