Measurements of scientific systems are always subject to variation, some more than others.
there are many structures for measurement error, and statisticians spend a great deal of time modeling these errors.
suppose the measurement error x of a certain physical quantity is decided by the density function
f(x)=k(3−x2), for −1≤x≤1,
f(x)=0, elsewhere.
(a) determine k that renders f(x) a valid density function.
(b) find the probability that a random error in measurement is less than 1/2.
(c) for this particular measurement, it is undesirable if the magnitude of the error (i. e., |x|)
exceeds 0.8. what is the probability that this occurs?

Over the course of the school year, you keep track of how much snow falls on a given day and whether it was a snow day. your data indicates that of twenty-one days with less than three inches of snow, five were snow days, while of the eight days with more than three inches of snow, six were snow days. if all you know about a day is that it is snowing, what is the probability that it will be a snow day?

Which function can be used to model the monthly profit for x trinkets produced? f(x) = –4(x – 50)(x – 250) f(x) = (x – 50)(x – 250) f(x) = 28(x + 50)(x + 250) f(x) = (x + 50)(x + 250)
