Identify if the random variable is a DISCRETE or CONTINUOUS. Weight of students in a university CONTINUOUS rue or False: As the sample size increases, the standard error increases.
In a normal curve, the mean is located at the: midpoint of the curve; intersection of the lowest and highest point; lowest point of the curve; highest point of the curve highest point of the curve Which of the following is incorrect?: Probability distribution equals to zero.; Probability distribution is used to compute discrete random variables; Probability distribution is used to compute continuous random variables; None of the choices; Probability distribution equals to one. Probability distribution equals to zero. True or False: Sampling Error is the degree of error expected for a given sample design
TRUE
True or False: One of the most important characteristics of any probability distribution is the mean. True
True or False: The formula of mean is relative to compute for the variance.
True or False: Random sample happened when data is collected in no certain order
Given the set of data: 1, 1, 2, 2, 3, 3, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22 Find the lower quartile : 8; 0; 3; 3,4,5,6,7,8,9,10,11,12, 8
