Centers for Disease Control and Prevention reported in 2012 that 1 in 88 American children had been diagnosed with an autism spectrum disorder (ASD). Suppose that a random sample of 200 American children is selected, and let X count the number of children in the sample that are diagnosed with ASD. (Hint: The distribution of X will be approximately what?) Selectallthatapply: If the sample size is 352, the standard deviation of the number who have been diagnosed with ASD is approximately 1.32 The expected value of the number who have been diagnosed with ASD is approximately 2.27. The standard deviation of X is approximately 1.5. If the sample size is 352, the expected value of the number who have been diagnosed with ASD is approximately 2.33
