Employee retention is a major concern for many companies. A survey of Americans asked how long they have worked for their current employer . Consider the following sample data of 2000 college grad who graduated 5 years ago. Time w/Current Employer(yrs) Number 1 506 2 390 3 310 4 218 5 576 Let x be the random variable indicating the # of yrs the respondent has worked for her/his current employer. a. Use data to develop an empirical discrete probabilty for x. b.Show that probabilty satisfiesconditions of the valid discrete probabilty. c.What is the probability that a respondent has been at his/her current place of employment for more than 3 yrs.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
