Streaming Devices ~ Consider the random variable X = number of digital streaming devices found in U. S. homes. Provided below are two probability models for this variable, one for the population of all U. S. households WITH children and the other for the population of all U. S. households WITHOUT children. Use these two discrete models to answer the following questions. Question 7 Subquestions 7.a 0.5 point(s) Based on these models, the expected value for the number of digital streaming devices found in U. S. households WITH children is the expected value for the number of digital streaming devices found in U. S. households WITHOUT children. equal to larger than smaller than 7.b 0.5 point(s) Based on these models, the standard deviation for the num
