In a study of government financial aid for college students, it becomes necessary to estimate the percentage of full-time college students who earn a bachelor's degree in four years or less. find the sample size needed to estimate that percentage. use a 0.03 margin of error and use a confidence level of 95%. complete parts (a) through (c) below. a.) assume that nothing is known about the percentage to be estimated. n=b.)assume prior studies have shown that about 55%of full-time students earn bachelor's degrees in four years or less. n=c. does the added knowledge in part (b) have much of an effect on the sample size?

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
