The random variable x is observed twice. Find E(x) = . Then use the sampling distribution of x to find the expected value of x. Click the icon to view the table. Find E(X) = H. E(x) = (Round to the nearest tenth as needed.) Find the expected value of x using the sampling distribution of x. E(x) = (Round to the nearest tenth as needed.)An investigation of the ability of a hybrid tomato plant to produce a certain protein found that the amount x of the protein produced in the plant had a mean of 107.7 micrograms per gram of fresh weight with a standard deviation of 7.9. Consider a random sample of n = 63 hybrid tomato plants and let x represent the sample mean amount of the protein produced. Would it be expected to observe a value of x less than 106 micrograms per gram of fresh weight? Explain. Consider an event with a probability less than 0.05 unlikely. Select the correct choice below and fill in the answer box within your choice. (Round to four decimal places as needed.) O A. It would be expected to observe a value of x less than 106 micrograms per gram of fresh weight because the probability of such an event is which is not unlikely. O B. It would not be expected to observe a value of x less than 106 micrograms per gram of fresh weight because the probability of such an event is which is not unlikely. O C. It would be expected to observe a value of x less than 106 micrograms per gram of fresh weight because the probability of such an event is which is unlikely. O D. It would not be expected to observe a value of x less than 106 micrograms per gram of fresh weight because the probability of such an event is which is unlikely
