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…

Three items are drawn in randomly from a population of 7 items. The item drawn may be defective or non-defective. Random variable is the occurrence of non-defective items. Total defective items in the population are two.a. Make a frequency distribution table of the random variable. b. Find the expected value of non-defective items in the random experiment.
Example: Suppose the mean of the number of unproductive days for a certain large segment of the population in a given year is 5.4 and the standard deviation is 2.8 days. Find the probabilities that average number of unproductive days of a random sampling of 49 from this environment is: a. more than 6 days b. between 4 and 6 days.
A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 22 tablets, then accept the whole batch if there is only one or none that doesn't meet the required specifications. If a particular shipment of thousands of aspirin tablets actually has a 6% rate of defects, what is the probability that this whole shipment will be accepted? ... The probability that this whole shipment will be accepted is (Round to three decimal places as needed.)
