In the probability distribution to the right, the random variable X represents the number of marriages an individual aged 15 years or older has been involved in. Compute and interpret the mean of the random variable X Px = marriages (Type an integer or a decimal. Do not round.) Which of the following interpretations of the mean is correct? O A. If many randomly selected individuals aged 15 years or older were surveyed, the observed number of marriages will be equal to the mean number of marriages for most individuals. OB. If many randomly selected individuals aged 15 years or older were surveyed, the observed number of marriages will be less than the mean number of marriages for most individuals OC. If many randomly selected individuals 40 to 49 years of age were surveyed, the sample mean number of marriages should be close to the mean of the random variable. OD. If many individuals aged 15 year or older were surveyed, the sample mean number of marriages should be close to the mean of…

A psychology quiz consists of 20 multiple chice questions with five possible answers for each question. A student, say John, is totally unprepared so randomly guesses the answer to each question. This means that John has a probability of 1/5 = .20 of getting any particular problem correct. Let X equal the number of questions out of the 20 questions that John gets correct. Do the calculations below using R. i. What is the variance of the randnm variahle Y = 2X?
