4. A recent study shows that 3 out of 5 elementary school students spend more time playing video games than studying during school days. Suppose a random and independent sample of 15 students is taken from this group. (8%) a. Can we assume binomial distribution for the number of children who spend more time playing video games than studying? Explain the reason. b. What is the probability that exactly 8 of these children were the ones who spend more time playing video games than studying? (Use the binomial formula and show your work) c. What is P(6SX<11)? (Use the binomial table and show your work) d. Use normal distribution (approximation) to answer part c. Is your answer similar to part c? Show your work
