An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e. g. 98.7654). x f(x) 0 1 2 3

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.

The standard deviation for a set of data is 5.5. the mean is 265. what is the margin of error?
