In the following probability distribution, the random variable x represents the number of activities a 3 4 1 0.084 P(x) 0.387 0.261 0.183 0.085 The mean is 1.495 activities. (Type an integer or a decimal. Do not round.) Which of the following interpretations of the mean is correct? A. As the number of experiments increases, the mean of the observations will approach the mean O B. The observed value of an experiment will be equal to the mean of the random variable in most e O C. The observed value of an experiment will be less than the mean of the random variable in most O D. As the number of experiments decreases, the mean of the observations will approach the mean e (d) Compute the standard deviation of the random variable x. The standard deviation is 1.4 activities. (Round to one decimal place as needed.) (e) What is the probability that a randomly selected student has a parent involved in three activities? The probability is (Type an integer or a decimal. Do not round.)
